Notes:
The ternary copolymerization of carbon dioxide with 1,2-epoxybutane and other epoxybutane isomers using the diethylzinc/water system as catalyst was carried out to investigate the relative reactivity between epoxides. cis-2,3-Epoxybutane was much more reactive than trans-2,3-epoxybutane in the copolymerization with carbon dioxide. The copolymer obtained from the reaction of carbon dioxide and cis-2,3-epoxybutane upon hydrolysis gave threo-2,3-butanediol, indicating the exclusive inversion of configuration in the ring-opening of the epoxide. In the formation of cyclic carbonate as a byproduct of the copolymerization, cis-2,3-epoxybutane and trans-2,3-epoxybutane exhibited a similar reactivity.
