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-azoleacetonitriles. The adaptability of halogen atoms for the cross-coupling reaction was investigated. The reaction of 4-halo-1,2-azoles was also examined.
在四(三苯基膦)钯(0)的催化作用下,经由卤代1,3-唑(1,3-噁唑、1,3-噻唑及咪唑)与苯磺酰丙腈在碱性条件下的缩合反应,合成了α-苯磺酰基-1,3-唑乙腈类化合物。探讨了卤素原子在交叉耦合反应中的适应性,并对4-卤代1,2-唑的反应进行了研究。
