2018年5月17日 · Aromatic rings will form C-C bonds when treated with alkyl or acyl halides in the presence of a strong Lewis acid (e.g. AlCl 3). These are known as Friedel Crafts reactions and are examples of electrophilic aromatic substitution reactions. The Lewis acid coordinates to a lone pair on the halogen, making the halogen a better leaving group.

So CH2Cl2 should be the reagent to form a cationic species for the polymerization. In addition, the experiment said it is a cationic polymerization of styrene and if CH3Cl is used, the mechanism is sensible.

2024年4月14日 · AlCl3/CH3CN 和 AlBr3/CH3CN 是【Bull. Chem. Soc. Jpn., 1995, 68, 2033】一类常用的去甲基化方法，其操作类似BBr3的使用，只是一般反应温度在0℃到室温。另外加入硫化物，由于硫的亲核性更强，可以增加反应活性。AlBr3/EtSH,AlCl3/EtSH, AlCl3/HSCH2CH2SH体系的活性很高，分子中酯、醛 ...

我做的是醚键断裂反应，用的是AlCl3/CH2Cl2，回流12小时后加过量盐酸冰混合物，氯仿萃取有机相，得红褐色液体，但是现在有很多奇怪的地方，请教大虫们！

2023年4月27日 · AlCl3 is not very soluble in DCM but it dissolves enough to do reactions with it in DCM. If you need a more soluble version of AlCl3, use MeAlCl2 instead

2015年2月21日 · SYNTHESIS: A suspension of 140 g anhydrous AlCl3 in 400 mL CH2Cl2 was treated with 100 g acetyl chloride. This slurry was added to a vigorously stirred solution of 110 g p-dimethoxybenzene in 300 mL CH2Cl2. Stirring was continued at ambient temperature for an additional 40 min, then all was poured into 1 L water and the phases separated.

A solution of AlCl 3 in CH 2 Cl 2 prepared in advance was used 18 days after the mixing of the components as an initiation system in the polymerization of isobutylene performed in CH 2 Cl 2 in the temperature range between −10 and −20°C.

2014年3月7日 · The reaction of AlCl3 with Me2E (E = S, Se or Te) or (n)Bu2E (E = Se or Te) in CH2Cl2 under rigorously anhydrous conditions gave the pseudo-tetrahedral complexes [AlCl3 (R2E)]. The [AlX3 (Me2E)] (X = Br or I, E = S; X = Br, E = Te) were made from toluene solution since attempted syntheses in CH2Cl2 resulted in substantial chloride incorporation.

Propose a reasonable mechanism to explain the following reaction. There’s just one step to solve this. In this reaction, benzene reacts with methylene chloride in presence of lewis base (A l C l …

Our expert help has broken down your problem into an easy-to-learn solution you can count on. Here’s the best way to solve it. Examine how the lone pair electrons on the chlorine atom interact with the AlCl3 molecule. Not the question you’re looking for? Post any question and get …
