Abstract

<p>t-BuP(NH2)(2) reacts with base-stabilized group 13 trihydrides with adduct formation (THF-BH3), with reduction to give t-BuPH2 (Me3N-AlH3) and with elimination of H-2 and formation of a metallonitridophosphinate (Me3N-GaH3). In contrast, the reaction with Cp*TiMe3 proceeds with formation of the four-membered heterocycle [t-Bu(H)P(NH)(2)Ti(Cp*)Me-2]. The aluminonitridophosphinate [t-Bu(H)P(NH)(2)AlMe2](2), reacts with C-H acidic reagents such as ROH, H2O with protonation of the N atom and subsequent formation of t-BuP(NH,),. This general reaction sequence was used for the synthesis of the first alumino(oxo)nitridophosphinate [t-Bu(H)P(NH)OAlMe2](2). The compounds were characterized by spectroscopic methods (H-1, C-13, IR, mass spectrometry) and single crystal X-ray diffraction ([t-Bu(H)P(NH)(2)Ti(Cp*)Me-2], [t-Bu(H)P(NH)OAlMe2](2)).</p>
