Visão geral

(S)-(−)-Styrene oxide is an oxirane derivative, which is used as a monomer for the synthesis of polyesters with relatively high Tg values via ring-opening copolymerization. It can also be used as a useful intermediate in the preparation of levamisole, a nematocide and anticancer agent.

(S)-(−)-Styrene oxide can undergo copolymerization with CO2 to form the corresponding polycarbonate in the presence of a cobalt-based catalyst system.
