Sustainable Synthesis, NMR and Computational Study of Isobutylmesitylphosphine

Abstract

The alkyl‐aryl‐substituted secondary phosphines i‐Bu(Mes)PH and Cy(Mes)PH are obtained from the reaction of the electrochemically generated organonickel sigma‐complex [NiBr(Mes)(bpy)] (Mes=2,4,6‐trimethylphenyl; bpy=2,2′‐bipyridine) with primary phosphines i‐BuPH2 and CyPH2, respectively. Detailed multinuclear NMR spectroscopy and quantum‐chemical calculations were used to assign the diastereotopic protons of i‐Bu(Mes)PH.

Recent Advances in Chemistry of Unsymmetrical Phosphorus-Based Pincer Nickel Complexes: From Design to Catalytic Applications

“…However, in modern literature, there is an increasing interest in the development of catalysts based on non-precious metals. For example, nickel, which is a more affordable low-cost and high-natural-abundance analogue of platinum and palladium, has attracted increasing attention in the catalytic chemistry of transition metals in recent years [ 1 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 ]. Thus, this mini-review is devoted to the recent advances in the chemistry of unsymmetrical phosphorus-based pincer nickel complexes, including the ligand design, the synthesis of nickel complexes and their catalytic applications.…”
