This manuscript describes the Ni-catalyzed coupling of azoles with aromatic nitriles. The use of BPh3 promotes these arylations with electronically diverse azoles and benzonitriles. While the nickel catalyst is necessary for the arylations of phenyl oxazoles, arylation of benzoxazoles with some nitriles affords the arylated products even in the absence of the Ni catalyst albeit in lower yield than
该手稿描述了Ni催化的唑类化合物与芳族腈的偶联。BPh 3的使用可促进电子形式多样的唑和苄腈的这些芳基化。尽管镍催化剂对于苯基恶唑的芳基化是必需的,但是即使在不存在Ni催化剂的情况下,苯并恶唑与某些腈的芳基化也可以提供芳基化的产物,尽管收率比催化方法低。与未催化的转化相比,镍催化的方法显示出更高的速率和更广阔的范围。
