Abstract

A user-friendly and highly efficient mechanochemical synthesis of Ni/NHC complexes of the general formula (NHC)Ni(Cp)Cl (NHC is an N-heterocyclic carbene ligand; Cp is the cyclopentadienyl anion) under aerobic conditions is reported. The reaction between nickelocene and azolium salts (NHC proligands) proceeds with good to excellent yields of (NHC)Ni(Cp)Cl in the presence of a K2CO3 additive, which reduces the clumping of the reaction mixture. The developed process can be scaled up on a planetary ball mill.

一种新的环戊二烯型Ni/NHC配合物的机械化学合成方法
一种方便、高效的机械化学合成Ni/NHC配合物的通式(NHC)Ni(Cp)Cl (NHC)是n -杂环碳配体;Cp是环戊二烯阴离子)在好氧条件下的报道。在K2CO3添加剂的存在下,二茂镍与氮盐(NHC前配体)的反应得到了(NHC)Ni(Cp)Cl的良好收率,减少了反应混合物的结块。所开发的工艺可以在行星球磨机上按比例放大。

期刊介绍: Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications. Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
