significantly slowed the development of the catalytic asymmetric hydroarsination reaction despite it being a highly attractive C-As bond formation methodology. In addition, there is a poor understanding of the main reaction steps in such reactions which limit further development in the field. Herein, key intermediates of the hydroarsination reaction catalyzed by a PCP NiII -Cl pincer complex are presented upon
尽管合成挑战是一种极具吸引力的C-As键形成方法,但它极大地减缓了催化不对称加氢砷化反应的发展。另外,对于此类反应中的主要反应步骤知之甚少,这限制了该领域的进一步发展。在此,在通过DFT计算,电导率测量,NMR光谱和催化筛选研究反应时,给出了由PCP NiII -Cl夹杂物催化的氢化砷化反应的关键中间体。然后将提出的新颖的Ni-Cl-As相互作用与已知的NiII催化的氢磷酸化反应进行对比,以突出它们之间的差异,即使P和As具有密切的基团关系。最后,
