The stereospecific ionic ring-opening polymerization of various donor-acceptor cyclopropanes is reported. The chiral cyclopropane monomers are readily prepared with established methodology and stereospecific polymerization is best conducted with a catalytic amount of MgBr serving as a Lewis acid and as an initiator. Polymers with molecular masses of up to 7800 g mol containing a stereocenter in every repeating unit are obtained and the substituents of the monomers can be readily varied to access a novel class of chiral polymers.
报道了各种供体-受体环丙烷的立体定向离子开环聚合反应。手性环丙烷单体可通过既定方法轻松制备，立体定向聚合反应最好在催化量的MgBr作为路易斯酸和引发剂的条件下进行。得到了每个重复单元都含有一个立体中心、分子量高达7800 g/mol的聚合物，并且单体的取代基可以很容易地改变，以获得一类新型的手性聚合物。
