SILYL-NITROGEN COMPOUNDS, II: SYNTHESIS AND CHARACTERISATION OF TETRASILA-PHOSPHA AND TETRASILA-ARSA TETRAZENES

Lithylated bis(trimethylsilyl)hydrazines, Li2N2(SiMe3)2 and LiHN2(SiMe3)2 react with (Me3Si)2NECl2 (E = P or As) to form hetero atom incorporated tetrazenes, 1,3,4,4-tetrakis(trimethylsilyl)-2-phospha-1-tetrazene (Me3Si)2N-N(SiMe3)-P=NSiMe3 and 1,1,4,4-tetrakis(trimethylsilyl)-2-arsa-2-tetrazene (Me3Si)2N-N=As-N(siMe3)2.The former thermolyses primarily into trisila-phosphatriazene (Me3Si)2N-P=NSiMe3 and tetrasilahydrazine (Me3Si)4N2, whereas, the latter forms tris(trimethylsilyl)hydrazine (Me3Si)3N2H.Phosphatetrazene interacts with CH3OH in an oxidative addition reaction to form -(trimethylsilylimino)-(methoxy)-phosphorane, Me3Si)2N-N(SiMe3)-PH(OCH3)(=NSiMe3), whereas, arsatetrazene undergoes cleavage reaction to yield (Me3Si)3N2H.
