1-Phosphino-2-sulfenylferrocenes: efficient ligands in enantioselective palladium-catalyzed allylic substitutions and ring opening of 7-oxabenzonorbornadienes†
Abstract
The readily available 1-phosphino-2-sulfenylferrocenes 1 provide very high enantioselectivities in Pd-catalyzed allylic substitution reactions and alkylative ring opening of
