In a pinch: The nickel pincer complex 1 catalyzes the cross‐coupling of the title compounds with remarkable substrate scope and functional group tolerance. A nickel/alkynyl species was isolated and shown to be catalytically competent. THF=tetrahydrofuran, O‐TMEDA=bis[2‐(N,N‐dimethylaminoethyl)] ether.
紧要关头:镍钳配合物1催化标题化合物的交叉偶联,具有显着的底物范围和官能团耐受性。分离出镍/炔基物质,并显示出催化能力。THF =四氢呋喃,O-TMEDA =双[2-(N,N-二甲基氨基乙基)]醚。
