Pentakis(trimethylsilyl)-3-phospha-2-pentazene (Me3Si)2N-N(SiMe3)-P=N-N(SiMe3) 2 (1) reacts with Me3COH to form oxidative addition products, the partially desilylated [bis(trimethylsilyl) hydrazino][bis(trimetriylsilyl)hydrazono](t-butoxy)phosphorane (2) and the completely desilylated hydrazino-hydrazono(t-butoxy) phosphorane (3). With CF3COOH, (1) forms [tris(trimethylsilyl) hydrazino] [bis(trimethylsilyl)hydrazono](trifluoroacetato)phosphorane (4). (1) and CF3COOH in the ratio 1:5 produce a partially desilylated oxidative addition product trimethylsilylhydrazino-trimethylsilylhydrazono(trifluoroacelato)phosphorane (5) and a desilylated dimer [H2N - N - P (OOCCF3) = N-NH2]2, (6). With fluorosulfonic acid, (1) forms tetrakis(trimethylsilyl) tetrazane (Me3Si)2N-NH-NH-N(SiMe3)2 (7) and a desilylated phosphorane H2N-NH-P(H) (SO3F)=N-NH2 (8). Trifluorornethane sulfonic acid forms a desilylated phosphorane H2N-NH-P(H)(SO3CF3) = N-NH2 (9).
