Preparation and reaction of quinolinyl (or pyridinyl)phosphonium salts with base and pivalaldehyde

α- and γ-Heteroaryltriphenylphosphonium iodides were prepared by reaction of the corresponding heteroaryl iodides with triphenylphosphine. Reaction of β-heteroaryl iodides with triphenylphosphine in the presence of a palladium catalyst gave β-heteroaryltriphenylphosphonium iodides. Elimination of the heteroaryl group was achieved by treating the heteroaryltriphenylphosphonium iodides with a base. Further, the heteroaryl group was trapped with pivalaldehyde to introduce a pivaloyl substituent onto the heteroaromatic ring.
