Abstract: The lithium salt of [bis (dicyclohexylamino) phosphanyl] diazomethane (7) reacts with bis (diclohexy1amino)-chlorophosphane (8) leading to a mixture of nitrilimine 9 and diazo derivative 10, in a 21/4 ratio. The reaction of [bis-(diisopropylamino) thioxophosphoranyl](trimethy1stannyl) diazomethane (1 1) with bis (diisopropy1amino) chloroborane (12) gives C-[bis (diisopropylamino) thioxophosphoranyl]-N-[bis ( ...
