Cyclo-Isomerization Reaction
Cyclomerization was a reaction that could use simple and readily available starting materials to construct complex ring systems. For example, in organic chemistry, the ring-closing enyne metathesis (RCEYM) in the enyne metathesis reaction belonged to the ring Isomerization reaction. The reaction mechanism was first reported to use Paladin (II) and Platinum (II) salt, and the mechanism was different from the metal carbene-induced pathway. However, Ruthenium carbenes were currently the preferred catalyst for this reaction. In 1995, Wender's research group and Shintani/Hayashi's research group used the Ru complex to catalyze the formal (5 + 2) cycloaddition reaction of cyclopropylethynes 5. In 2006, Echavarren's research group used the Ru (I) complex as a pi-Lewis acid catalyst to realize the cyclo-crystallization reaction of cyclopropylethynes 7. Bernd Plietker's research group at the University of Stuttgart used ((Ph P)^Fe2 (NO)(CO)) BF2 to catalyze the cycloolation/C-C bond activation reaction of cyclopropylethynes to achieve the synthesis of a series of n,5,4 -tricyclical skeletons commonly found in natural products. In addition, Professor Wang Yifeng, Professor Fu Yao, and Associate Professor Zhang Fenglian of the University of Science and Technology of China jointly designed a chiral-nitrogen-heterotacyclic-carbyne (NHQ)-boron-free radical catalyst. Using its function of catalyzing the inner-molecular cyclosporidation, they realized the symmetrical catalyst reaction through different reaction steps and constructed the corresponding ring-shaped product.

Reaction Diagram of Alkane and Halogen
There were several reactions between the two: 1. ** Substitute Halogenation **: - ** Substituted Halogenation on Aromatic Ring **: It is suitable for aromatic compounds. During the reaction, the hydrogen atom on the aromatic ring is replaced by a halo atom. - ** Aromatic ring side chain and fatty carbon substitution: For aromatic ring side chain and fatty carbon, the hydrogen atom in the structure can be replaced by a halo atom. Among these substitution and substitution, chloride-bromination was more common. 2. ** addition reaction **: An addition reaction between an unsatured carbon (such as a carbon-carbon double bond or a carbon-carbon triple bond) and a single substance such as a halo, hydrogen, etc., thereby introducing a halo atom into the unsatured carbon molecules to form a halo carbon. For example, when an alkene reacted with a single substance, the carbon-carbon double bond would be broken, and two halo atoms would be added to two carbon atoms. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Experimental Exploration of Alkane Substitution Reaction
Research on Alkane Substitution Reaction Experiment
The following are some of the innovative studies on the substitution reaction of alkyls: * * I. Experiment Equipment ** 1. * * Using a variety of special instruments ** - With the introduction of a pH-sensor, the experiment results could be observed and analyzed directly in the experiment of the substitution reaction of the alkyls. For example, in a substitution reaction using portable gas (the main components of the ane) as the source of the alkyls, the possible changes in the reaction process could be monitored in real time through the pH-sensor, which would help to understand the process of the reaction and possible side reactions. - A three-necked flask, a 50-milliliter syringe, a 23W incandescent lamp, aluminum foil, a single-hole rubber stopper, a guide tube, a water-stop clamp, a 500-milliliter beaker, an iron stand (with two iron clips and an iron ring), and other equipment were used to construct the experimental device. The three-necked bottle could easily add a variety of reagents and control the reaction conditions; the syringe could accurately control the amount of gas or liquid reagents added; the incandescent lamp provided the illumination conditions needed for the reaction, etc. 2. * * Combined with modern technology ** - The real-time projection technology could provide feedback on the students 'experiment situation in a timely manner. When students in chemistry clubs or interest groups carried out extra-cursory exploration experiments on the substitution reaction of alkyls, teachers and other students could clearly see the experimental operation process, reaction phenomena, etc. through the projection, so as to facilitate the discovery of problems, guidance, and communication. * * 2. Experimental Drug Development ** 1. * * Choose Special Reaction Material ** - The portable gas (mainly composed of Butane and Propane) was used as the source of the alkyls. This kind of material that was easy to obtain in life made the experiment closer to life. Compared with the traditional experiment using methane, it solved the problem that it was difficult to produce pure gas in large quantities. Butane and Propane could also reflect the substitution reaction characteristics of alkyls. - In terms of testing the reaction phenomenon, the use of reagents such as basic fuchsin could help to observe and verify the occurrence and process of the reaction from different angles. 2. * * Associate with other experimental drugs for innovation ** - In the preparation of Cl2, chemicals such as KmO2 solid, concentrated sulfuric acid, saturated salt water, and a solution of NaOx were used. The preparation of Cl2 was carried out through reasonable devices (such as conical flasks, double-hole rubber stoppers, separating funnels, pipes, water tanks, etc.). The saturated salt solution could be used for drainage and gas collection operations, and the NaOx solution could be used for tail gas treatment. The combination and usage of these drugs made the entire experimental drug system more perfect and environmental friendly. * * 3. The innovation of experimental design ideas ** 1. * * Reaction combination innovation ** - Combining the organic substitution reaction with the experiment of the mineral fountain. Since the substitution reaction of alkyls was a reaction that reduced the volume of gas, it could theoretically be combined with the fountain experiment in compulsory subject 1. This combination increased the interest of the experiment. For example, when the substitution reaction was carried out with a ane or a ane, the change in the gas volume after the reaction could be visualized through a phenomenon similar to a fountain experiment, which would help students better understand the reaction principle. 2. * * Design based on curriculum integration ** - Combining the knowledge of the first section of the third chapter of the compulsory high school chemistry textbook,"The simplest organic matter--methane", and the first section of the second chapter of the elective book,"Fatty Alkane", according to the students 'cognitive level, the experiment was designed for the students of the chemistry club or interest group. This kind of design idea that integrated knowledge from different courses would help students understand the principle of the substitution reaction more deeply and comprehensively. They would also discover problems and phenomena that were not noticed in the textbook during the experiment process, and cultivate students 'scientific attitude, questioning spirit, and innovative consciousness. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Alkane substitution reaction consumes the most Cl2
In the substitution reaction between an alkyls and a hydrogen atom, one hydrogen atom could only be replaced by one hydrogen atom. To maximize the consumption of Cl2, all the hydrogen atoms in the alkyls were replaced by Cl2 atoms. According to the general formula of alkyls, the larger the number of hydrogen atoms, the more hydrogen atoms there were, and the more Cl2 would be consumed during the complete substitution. Theoretically, alkyls with infinite carbon number would consume the most Cl2 during the complete substitution reaction, but there was no specific alkyls with the largest number of hydrogen atoms. As long as the carbon number continued to increase, the amount of Cl2 consumed would continue to increase. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
