Studien zur Synthese, Struktur und Reaktivität heterozyklischer Metallonitridophosphinate

Studies on the Synthesis, Structure and Reactivity of Heterocyclic Metallonitridophosphinates t ‐BuP(NH 2 ) 2 reacts with base‐stabilized group 13 trihydrides with adduct formation (THF‐BH 3 ), with reduction to give t ‐BuPH 2 (Me 3 N‐AlH 3 ) and with elimination of H 2 and formation of a metallonitridophosphinate (Me 3 N‐GaH 3 ). In contrast, the reaction with Cp*TiMe 3 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 AlMe 2 ] 2 reacts with C‐H acidic reagents such as ROH, H 2 O with protonation of the N atom and subsequent formation of t ‐BuP(NH 2 ) 2 . This general reaction sequence was used for the synthesis of the first alumino(oxo)nitridophosphinate [ t ‐Bu(H)P(NH)OAlMe 2 ] 2 . The compounds were characterized by spectroscopic methods ( 1 H, 13 C, IR, mass spectrometry) and single crystal X‐ray diffraction ([ t ‐Bu(H)P(NH) 2 Ti(Cp*)Me 2 ], [ t ‐Bu(H)P(NH)OAlMe 2 ] 2 ).
