The hydrophosphination of carbon-carbon multiple bonds has been generally performed under acid, base or metal catalysis in different solvents. Herein, alkyl and alkenyl tertiary phosphines are obtained by the addition...

Novel tetranuclear organocopper(I) clusters bridged by two halides and two indolyl-based NCN pincer ligands were synthesized through the reactions of Cu(I) halides with lithiated ligands. Single-crystal X-ray diffraction revealed that the structure of these complexes included a [Cu4X2]2+ cluster unit wherein the four copper ions were stabilized by multiple Cu–Cu interactions, arranged in a distorted
通过 Cu( I ) 卤化物与锂化配体的反应,合成了由两个卤化物和两个基于吲哚基的NCN钳形配体桥接的新型四核有机铜 ( I ) 簇。单晶 X 射线衍射表明,这些配合物的结构包括一个 [Cu 4 X 2 ] 2+簇单元,其中四个铜离子通过多个 Cu-Cu 相互作用稳定,以扭曲的四面体方式排列,卤化物阴离子μ 3 -与金属中心桥接。同时,这些团簇在无溶剂条件下对烯烃的氢磷酸化表现出优异的催化活性,具有广泛的官能团耐受性。

metal-free approach for the cross-coupling of arenes or styryl–thianthrenium salts (TTs) with diarylphosphines via an electrondonor–acceptor (EDA) complex. Various tertiary phosphines were obtained with high site selectivity and good functional group tolerance. This method enables straightforward construction of C–P bonds via C–H activation of arenes and allows the late-stage functionalization of natural
