Palladium-catalyzed cross-coupling reaction of haloazoles with phenylsulfonylacetonitrile

Sakamoto,Kondo,Suginome,Ohba,Yamanaka

, p. 552 - 554 (2007/10/02)

Condensation of halo-substituted 1,3-azoles (1,3-oxazoles, 1,3-thiazoles and imidazoles) with phenylsulfonylacetonitrile under basic conditions was promoted by catalytic action of tetrakis(triphenylphosphine)palladium(0) to give α-phenylsulfonyl-1,3-azole
