A novel, air-stable phosphine ligand, prepared from readily available 2-bromonitrobenzene and vinylmagnesium bromide, combines with Pd(CH3CN)2Cl2 to afford an effective catalyst for Suzuki−Miyaura cross-coupling of aryl, heteroaryl, and allyl chlorides with phenylboronic acid.
An efficient catalytic amination of aryl-substituted allylic alcohols has been developed. The complex [(eta(3)-allyl)PdCl](2) modified by a bis phosphine ligand, L, has been used as catalyst in the reaction that afforded a wide range of allyl amines in good to excellent yield under mild conditions.
