A novel strategy, based on the in situ generated boron-thexyl-silaboracyclic initiating sites for the polyhomologation of dimethylsulfoxonium methylide, has been developed for the synthesis of complex polyethylene-based architectures. As examples, the synthesis of a 4-arm polyethylene star, three (polystyrene)(polyethylene)2 3-miktoarm stars and a PE-branched double graft copolymer is given.
基于原位生成的硼-叔丁基-硅硼环引发位点用于二甲亚砜甲基化物的多聚同系化反应，已开发出一种新策略用于合成复杂的聚乙烯基结构。作为示例，给出了四臂聚乙烯星型聚合物、三种（聚苯乙烯）（聚乙烯）₂三臂星型聚合物和一种聚乙烯支化双接枝共聚物的合成方法。
