The bifunctional title compounds 2 react with acylating, carbamoylating and sulfonylating reagents mostly at the primary amino group of the hydrazine function.Both functional groups of 2 are attacked by N,N'-carbonyldiimidazole converting it into 1H-1,2,4

In an efficient one-pot procedure, the title compounds (8) were obtained by the reaction of α-halo ketones (1) with potassium thiocyanate and monosubstituted hydrazines (3). The reaction is considered to proceed via the formation of azo-alkenes (5) and th
