cf. Ber. 34, 320(1901). PhNHNHCSNHPh (I) in Me2CO at -5°, treated with PhN2Cl in Me2CO, gives a vigorous evolution of N2, with the formation of the HCl salt, decomposes 205°, of S-phenyl-1,4-diphenylthiosemicarbazide (II), PhNHNHC(SPh):NPh, m. 75°. II is easily degraded by alkali into I and PhSH. The mother liquor from II yields benzeneazophenyliminomethane thiophenyl ether (III), PhN:NC(SPh):NPh, red, m. 115°; this is the oxidation product of II and is formed from II with H2O2 or yellow HgO; III gives II with (NH4)2S. The p-nitrophenyl homolog of II forms a HCl salt (IV), pale yellow, decomposes 205°; the free base is so susceptible to hydrolysis that NH4OH in EtOH gives (p-O2NC6H4S)2. With HCHO IV yields the diphenyldihydrotriazole ether of p-nitrothiophenol, PhN.N:C(SC6H4NO2).NPh.CH2, m. 127°; BzH gives the tri-Ph homolog, PhN.N:C(SC6H4NO2).NPh.CHPh, brownish rose, m. 124°. The red azo compound m. 118°. (PhNH)2CS and p-O2NC6H4N2Cl (V) in EtOH-Me2CO at -5° give S-p-nitrophenyldiphenylisothiourea (VI), PhNHC(SC6H4NO2):NPh, light yellow, m. 131°; on recrystallization from EtOH partial decomposition occurs into (PhNH)2CO and p-O2NC6H4SH; alkali gives complete hydrolysis. The p-Br derivative of VI, p-BrC6H4NH(CSC6H4NO2):NPh, light yellow, m. 158°, results in 75% yield from p-BrC6H4NHCSHPh. CS(NH2)2 and PhN2Cl in Me2CO give [H2NC(:NH)S]2.2HCl, m. 173-4° (decomposition). V gives 84% of the compound H2NC(:NH)SN:NC6H4NO2 as the HCl salt; this salt decomposes in absolute EtOH at room temperature PhNHCO2Et and V in Me2CO at -5° give the p-nitrophenyl ether of p-nitrobenzenediazohydrosulfide (VII), O2NC6H4N:NSC6H4NO2, citron-yellow, decomposes 142°; it results in varying amounts by coupling different thiourethans with V. PhN:C(SH)OCH2Ph and V in EtOH-Me2CO give VII; in C6H6 there results the compound PhNHCOSC6H4NO2, m. 158°.
