Nickel(0) Triethyl Phosphite Complex-Catalyzed Allylic Substitution with Retention of Regio- and Stereochemistry

Nickel(0) triethyl phosphite complex-promoted reaction of allylic acetates with thiols produced allylic sulfides with retention of configuration without allylic rearrangement. A similar reaction of allylic acetates with alcohols and phenols also proceeded with retention of regio- and stereochemistry.
