Cumulated Ylides, IX. New Synthesis of N-substituted (Triphenylphosphoranylidene)ketenimines and (Triphenylphosphoranylidene)thioketene
Methylenetriphenylphosphorane (1) and isocyanidedichlorides resp. thiophosgene react in the molar ratio 3:1 to give N-substituted (triphenylphosphoranylidene)ketenimines 6A resp. (triphenylphosphoranylidene)thioketene 6B and methyltriphenylphosphonium chloride.The P-Cα-coupling constants in the 13C-NMR-spectra of 6 are in agreement with theoretical calculations.
