| Abstract: | Co(salen) catalyzes solvolytic ring opening of epoxy compounds in methanol to give glycol monomethyl ether derivatives. Active species is Co(salen) (OH) which is formed in situ, and its catalytic activity depends on the pKa of the conjugated acid of X in Co(salen) (X) (X=OAc, OCH2CF3, OH).
