Hydrolysis of 1,1,3,3-Tetrakis(dimethylamino)-1λ5, 3λ5 -diphospheteHydrolysis of 1,1,3,3-Tetrakis(dimethylamino)-1λ5, 3λ5 -diphosphet (2) yields in the first step Bis(dimethylamino)phosphorylmethyliden-methyl-bis(dimethylamino)phosphorane (5). In the second step Bis(dimethylamino)phosphoryl-methyl(dimethylamino)phosphosphonylmethylen (6) is the main product of hydrolysis. In addition small amounts of methylphosphonic-bis(dimethylamide) (7) are formed. Properties, nmr and mass spectra of 5 and 6 are described, their mechanism of formation is discussed.
Notes:
Die Hydrolyse von 1,1,3,3-Tetrakis(dimethylamino)-1λ5, 3λ5 -diphosphet (2) führt in erster Stufe zu Bis(dimethylamino)phosphorylmethyliden-methyl-bis(dimethylamino)phosphorane (5). In zweiter Stufe wird vornehmlich Bis(dimethylamino)phosphoryl-methyl(dimethylamino)phosphosphonylmethylen (6) neben geringen Mengen von Methylphosphonsphonsäure-bis(dimethylamid) (7) gebildet. Eigenschaften, NMR- und Massenspektren von 5 und 6 sind beschrieben, ihr Bildungsmechanismus wird diskutiert.
