Summary

The Stereoelective polymerization of methylthiirane was studied with the ZnEt2/(2S,3S)3-methyl 1,2-pentanediol initiator system. The stereoelectivity depends upon the diastereoisomeric purity of the diol and the experimental conditions of the initiator preparation. The presence of an additional asymmetric centre in the alkyl substituent significantly increases the stereoelectivity ratio as compared to that observed with the usual standard initiator system: ZnEt2/(R) 3,3-dimethyl 1,2-butanediol.
