Contributions to the Chemistry of Boron, 214. Synthesis and Reaction Chemistry of Aminophosphanylboranes

Aminochlorophosphanylboranes, (R2N)B(Cl)P(SiMe3)2 (1a-d) and (R2N)B(Cl)PH2 (2a-d), are obtained from elimination reactions between aminochloroboranes and LiP(SiMe3)2 and LiPH2, respectively.Selected reaction chemistry of (i-Pr2N)B(Cl) (1a) with NH3, Me3SiN3, Cr(CO)5*NMe3, and W(CO)5*NMe3 is described.The azide (i-Pr2N)B(N3)P(SiMe3)2 (12a) is stable at 25 deg C; however, thermolysis at 80 deg C provides a novel six-membered ring compound 2 (13a).The reaction of (Ph2N)B(Cl)P(SiMe3)2 (1b) with LiP(SiMe3)2 produces the only isolable bis(phosphanyl)borane (5b), while combination of (R2N)B(Cl)PH2 with LiPH2*DME yields new diphosphadiboretanes 6 2 (R2N = i-Pr2N, Ph2N and tmp = 2,2,6,6-tetramethylpiperidino) and triphosphatriborinanes 7 3 (R2N = (Me3Si)2N, Me2N and Et2N).Two salts, (8a) and (8c) (DME = ethylene glycol dimethyl ether) are also isolated.The results of molecular structure determinations for 2 (13a), 2 (4c), 2*Cr(CO)5 (7c), BPH>3 (4d), BPH>3*Cr(CO)5 (7d), (Ph2N)B2 (5b), and (8a) are discussed.Key Words: Boranes, amino-, phosphanyl-/ Diphosphadiboretanes / Triphosphatriborinanes
