feasibility of the addition of CCl4 to linear and cyclic olefins and dienes in the presence of chromium and ruthenium complexes was established. The influence of water as a nucleophilic additive and the influence of the olefin nature, the catalyst central atom, and its ligand environment on the reaction selectivity and product yields were investigated. It was shown that the addition of water to chromium and
建立了在铬和钌配合物存在下向直链和环状烯烃和二烯中添加CCl 4的可行性。研究了水作为亲核添加剂的影响以及烯烃性质,催化剂中心原子及其配体环境对反应选择性和产物收率的影响。结果表明,向铬和钌催化剂中加水会导致所得1,1,1,3-四氯衍生物中的氯甲基水解,产生相应的羟基衍生物并增加形成(1 + 1)加合物,这是由次氯酸的形成引起的,次氯酸是将CCl 4加至烯烃的助活化剂。
