A general, versatile method for alkylation and arylation of haloheterocyclic compounds is reported. In the presence of a catalytic quantity of [NiCl2(dppp)], where dppp stands for Ph2P(CH2)3PPh2, bromothiophenes, halopyridines, haloquinoline, and haloisoquinolines reacted with alkyl and aryl Grignard reagents at room temperature or at ether refluxing temperature to give the cross-coupling products
报道了卤代杂环化合物的烷基化和芳基化的通用方法。在催化量[NiCl 2(dppp)](其中dppp代表Ph 2 P(CH 2)3 PPh 2)的存在下,溴噻吩,卤代吡啶,卤代喹啉和卤代异喹啉在室温或室温下与烷基和芳基格氏试剂反应在乙醚回流温度下得到交叉偶联产物。偶联反应已应用于异喹啉生物碱的合成。还研究了2-噻吩基和2-吡啶基格氏试剂的反应性。
