A well‐defined organozinc complex, [MeOCH 2 CH(Me)OZn‐OCH(Me)CH 2 OMe] 2 [EtZnOCH(Me)CH 2 OMe] 2 ([Zn‐MP] 2, 2 ), is a very unique and versatile initiator for polymerization of oxirane and bioxirane. [Zn‐MP] 2, 2 induced “pure” isospecific polymerization of tert ‐butylethylene oxide. The two to two complex, however, became a syndiospecific initiator for cis ‐α, β‐disubstituted oxirane. Regioselective nature of [ZnMP] 2, 2 complex against bioxirane made it possible to prepare a soluble polyether having pendant oxirane rings.
