Reactivity of Rh(PMe3)4Cl with lithium derivatives of phosphorus-substituted diazomethanes. First evidence for a transient nitrogen-transition-metal nitrile imine. X-ray structure of (PMe3)2RhNBuNCHP(N-i-Pr2)2

Reaction at the diazo carbon atom occurred when the lithium derivative of [bis(diisopropylamino)thioxophosphoranyl]diazomethane and Rh(PMe3)4Cl were allowed to react. The 16-electron Rh(I)-C bonded diazo complex (PMe3)2RhC(N2)P(N-i-Pr2) 2(S) (1) containing a rhodium-sulfur bond was obtained. In contrast, when the lithium derivative of [bis(diisopropylamino)phosphino]diazomethane was used, the reaction took place at the terminal diazo nitrogen atom. The formation of (PMe3)2RhN-n-BuNCHP(N-i-Pr2)2 (2) is explained by the transient formation of a nitrogen-rhodium nitrile imine.
