General description
1-Chloro-1-cyclopentene undergoes cross-coupling reaction with arylboronic acids, arylzinc reagents and thiols catalyzed by air-stable palladium complexes to yield the corresponding styrene derivatives, biaryls, and thioethers. Palladium-catalyzed aminocarbonylations of 1-chloro-1-cyclopentene and benzyl amine has been studied.

Air-stable palladium complexes [(t-Bu)(2)P(OH)](2)PdCl(2), [(t-Bu)(2)P(OH)PdCl(2)](2), and [[(t-Bu)(2)PO...H...OP((t-Bu)(2)]PdCl](2) serve as efficient catalysts for a variety of cross-coupling reactions of vinyl and aryl chlorides with arylboronic acids, arylzinc reagents, and thiols to yield the corresponding styrene derivatives, biaryls, and thioethers.
