Experimental partAll experiments related to the polymerization reaction were carried out under nitrogen atmosphere to exclude oxygen and moisture.Reagents: (S)-3,3,3-Trifluoro-l,2-epoxypropane (TFEP; enantiomeric excess (e. e.) = 75) was prepared from 3,3,3-trifluoropropene by fermentation with Nocardia corallina by Nippon Mining Co. Ltd., and purified by distillation after refluxing over calcium dihydride. Commercial benzene, methanol and diethylzinc were purified by the usual methods '). 1,2-Dimethoxyethane, 1 -methoxy-2-propanol and 2-methyl-2-propanol were purified by distillation after refluxing over calcium dihydride. [C2H5ZnMP12[ZnMP212 (5)13) (MP: CH30CH2CH(CH3)O-) were prepared by the methods as previously reported. Alkali metal tert-Makromol. Chem., Rapid Commun.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
