The main product from the reaction between bis(dimethylamino)fluoromethylidene-phosphorane (1) and n-butyllithium in the presence of tetramethylethylenediamine is n-butyl-dimethylamino-methyl-(methylene)-phosphorane (7).As a by-product from the reaction between methyl-bis(dimethylamino)difluorophosphorane and n-butyllithium bis(dimethylamino)-methyl-(methylene)-phosphorane (9) was isolated in small yield.The new carbodiphosphoranes 7 and 9 are characterized by their 1H, 13C, and 31P NMR and mass spectra.Keywords: Diaminofluoromethylidenephosphorane, Carbodiphosphoranes, NMR Spectra, Mass Spectra
