1,2,4‐Triazin‐3‐ylthio‐, 1,2,4‐triazepin‐3‐ylthio‐, 1,2,4‐triazol‐3‐ylthio‐, and 1,2,4,3‐triazaphosphol‐5‐ylthio‐1,5‐benzodiazepines 4 – 20 were prepared via the reaction of 2‐oxo‐4‐phenyl‐2,3‐dihydro‐1 H ‐1,5‐benzodiazepin‐3‐ylhydrazonothiocarbamate ( 2 ) with halocompounds, dicarbonyl compounds, enaminones, 4‐chlorobenzaldehyde, 4‐chlorobenzylidenemalononitriles, N,N ‐dimethylformamide dimethylacetal, carbon disulfide, and 2,4‐bis(4‐methoxyphenyl)‐1,3,2,4‐dithiadiphosphetane‐2,4‐disulfide (Lawesson's reagent).
