2-Imino-1,3,4-selenadiazole derivatives can be synthesized from hydrazides and isoselenocyanates by sequential oxidation and a tributylphosphine (PBu3)-promoted annulation reaction at room temperature. In this synthetic process, crude less stab

A P(NMe2)3-mediated annulation reaction of N-Acyldiazenes with isothiocyanates, producing 2-imino-1,3,4-Thiadiazoles, is reported. This reaction proceeds well with crude N-Acyldiazenes derived from the oxidation of hydrazides by iodi

Benzeneseleninic anhydride (1; BSA) is an effective reagent for the mild regeneration of the carbonyl group from ketone phenylhydrazones, p-nitrophenylhydrazones, tosylhydrazones, oximes, and semicarbazones at 40-50 deg C.Tosylhydrazones and oximes of aldehydes are also readily converted into the parent aldehyde.The phenylhydrazone and p-nitrophenylhydrazone derivatives of aldehydes afford ketoazo-compounds.The ketoazo-species could also be prepared by oxidation of the corresponding hydrazide with compound (1).Both aromatic and aliphatic hydrazo-compounds and hydroxylamines can be oxidised to azo- and nitrozo-derivatives respectively.
