Formation of a Carbene–Phosphinidene Adduct by NHC‐Induced P–P Bond Cleavage in Sodium Tetramesityltetraphosphanediide

Abstract

Abstract The reaction of [Na 2 (thf) 4 P 4 Mes 4 ] ( 1 ) (Mes = 2,4,6‐Me 3 C 6 H 2 ) with 1,3‐dimethylimidazolin‐2‐ylidene (Me 2 Im) or the corresponding imidazolium iodide ([Me 2 ImH]I) leads to P–P bond cleavage and formation of the carbene–phosphinidene adduct (Me 2 Im)PMes ( 2 ), which was characterized by NMR spectroscopy, mass spectrometry, and X‐ray crystallography.
