Synthesis and Catalytic Activity of Quaternary Ammonium Salts Containing gem-Dichlorocyclopropane and 1,3-Dioxolane Fragments

Quaternary ammonium salts containing gem -dichlorocyclopropane and 1,3-dioxolane groups were synthesized in high yield. The reactions of dichlorocarbonation of styrene and O-alkylation of 2,2-dimethyl-4-hydroxymethyl-1,3-dioxolane in the presence of quaternary ammonium salts were studied. It was established that in the O-alkylation reaction, compounds containing cycloacetal and allyl moieties have the maximum efficiency in the series of catalysts studied. The structures of the isolated salts were proved by 1 H and 13 C NMR spectroscopy.
