HCID 2754918HCID 2754918, compoundYield 84%

Procedure

O,O-Diphenyl phosphorochloridothioate, (PhO)2P(S)Cl, (38 g, 0.13 mole) was added slowly to hydrazine hydrate, (25 g of 60% solution ≅0.47 mole hydrazine) at 65°-75° C. The mixture was allowed to cool slowly and the solid product was then recovered by filtration, washed with water and dried. Recrystallization from benzene/petroleum ether (1:1) gave 30.5 g product (84% yield) melting at 59°-61° C.
