Allylic acetates are reduced to alkenes by reductive displacement by hydride reagents via catalytic activation with Pd(0) complexes. In the absence of hydrides, allylic acetates afford conjugated dienes in DMSO solvent. Under suitable conditions, a number of a-bonded functional groups are susceptib

## Abstract Palladium(0)‐catalyzed allylation of nucleophiles such as morpholine, sodium dimethyl malonate and 2,6‐dimethylaniline can be achieved under very mild conditions using __N__‐allyl‐2,4,6‐triphenylpyridinium tetrafluoroborates as allylating reagents in reactions in which 2,4,6‐triphenylpy
The oxidative addition of the allylic acetate, CH 2 CH À CH 2 À OAc, to the palladium(0) complex [Pd 0 (P,P)], generated from the reaction of [Pd(dba) 2 ] with one equivalent of P,P (P,P dppb 1,4-bis(diphenylphosphanyl)butane, and P,P dppf 1,1'-bis(diphenylphosphanyl)ferrocene), gives a cationic (h
