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.

Partially substituted tetrazenes (Me3E)nN4H4-n (E = Si, Ge, Sn) can be prepared by protolysis of higher substituted tetrazenes (Me3E)oN4H4-o (o > n) or by silylation, germylation, or stannylation of lower substituted tetrazenes (Me3E)mN4H4-m (m 140 deg C1/2 = 3/4 h), of (Me3Si)2N-N=N-NH2 to Me3SiN3 and Me3SiNH2 (concentrated solution; τ40 deg C1/2 ca. 1/4 h), and of (Me3Si)HN-N=N-NH(SiMe3) to N2 and (Me3Si)2N-NH2 (dilute solution; τ140 deg C1/2 > 1 h) or to HN3 and (Me3Si)2NH (concentrated solution; τ140 deg C1/2 1 h).
