A novel nickel(I) complex (di(2,2′-(1-phenyl-1H-1,2,4-triazole-3,5-diyl)dipyridine))(dibromine) nickel(I)bromide ([Ni-N4]Br) exhibited extremely high efficiency toward the (de)hydrogenative alkylation of amines and alkyl heteroarenes by alcohols. The catalytic performance can be attributed to the functionalized nitrogen ligand, which adopts a cationic coordination mode and the facile dissociation of
一种新型镍(I)配合物(二(2,2'-(1-苯基-1 H -1,2,4-triazole-3,5-diyl)dipyridine))(二溴)镍(I)溴化物([ Ni-N 4 ]Br) 对胺和烷基杂芳烃通过醇的(脱)氢化烷基化表现出极高的效率。催化性能可归因于功能化的氮配体,它采用阳离子配位模式和配位水的容易解离。这种可持续转化适用于各种醇,在无溶剂条件下具有良好的官能团耐受性和高选择性。该合成策略为构建功能化胺和不饱和N-杂芳族衍生物提供了一种绿色高效的方法。
