Hydrofluorination of Bis(silylimido)tetramethyldiphosphoraneThe silylated bis(imidophosphorane), (CH3)2P[NSi(CH3)3]—P[NSi(CH3)3](CH3)2, 1 reacts in ether with hydrogen fluoride to give the tetrafluorodiphosphorane, (CH3)2PF2—PF2(CH3)2, 2, while hydrofluorination in fluorotrichloromethane gives the diazadiphosphetidin 3 and the iminophosphorane 4. The thermal decomposition of 2, studied by 19F and 31P-n.m.r. spectroscopy, yields trifluorodimethylphosphorane and tetramethyldiphosphane.
Notes:
Das silylierte Bis(imidophosphoran), (CH3)2P[NSi(CH3)3]—P[NSi(CH3)3] (CH3)2, 1 wird durch ätherischen Fluorwasserstoff in das Tetrafluordiphosphoran, (CH3)2PF2—PF2(CH3)2, 2 überführt, während die entsprechende. Hydrofluorierung in Fluortrichlormethan das N-Trimethylsilylfluordimethyl-diazadiphosphetidin 3 und Fluordichlormethyl-dimethyl-N(trimethylsilyl)iminophosphoran 4 liefert. 2 ist thermisch labil und zerfällt in Trifluordimethylphosphoran und Tetramethyldiphosphan.
