Silica-supported guanidinium chloride (PBGSiCl) exhibits efficient chemo- and regiospecific catalytic activity in the ring opening of epoxides with various electrophiles. This reaction allows the preparation of beta-chloro esters and beta-chloro chloroformates in high yield-under neutral conditions which offer product stability and ease of product isolation.
