Reactions of an Azidoborane with Phosphines: Synthesis of N-Boryliminophosphoranes
Abstract
A series of N-boryliminophosphoranes (compounds containing the B-N=P linkage) have been prepared by the reactions of a sterically hindered azidoborane, (Me3Si)2NB(Bu)N3 (1), with some three- and two- coordinate phosphines. Treatment of the (silylamino)phosphines (Me3Si)2NP(R)Me and the simple aminophosphine (Me2N)2PPh with 1 gave the corresponding four-coordinate N-boryliminophosphoranes, (Me3Si)2NP(R)(Me)=NB(tBu)N(SiMe3)2 (2: R = Ph; 3: = Me) and (Me2N)2P(Ph)=NB(tBu)N(SiMe3)2 (4). Similarly, the reactions of 1 with the two-coordinate phosphorus species, (Me3Si)2NP=ESiMe3 (E = CH, N), afforded the first N-borylimino derivatives of three-coordinate, pentavalent phosphorus, (Me3Si)2NP(=ESiMe)=NB(tBu)N(SiMe3)2 (5: E = CH; 6: E =N). Compounds 2-6 were characterized by NMR (1H, 13C,31P, and 11B) spectroscopy and elemental analysis.
