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

Thermolysis of the azoalkenes (1) and (6) - (8) takes place by 4π-electron electrocyclisation, followed by elimination of HCN to give imines. Decomposition of the related compounds (9)-(12) is less well defined, though the indole (22) has been identified from the thermolysis of (10) at high temperature. Alternatively, the azo ketones (15) - (18) undergo homolysis of the central C-N bond at 750 °C, and low yields of biaryls, formed by intermolecular radical coupling are generally found. Decarbonylation of intermediate aroyl radicals is extremely rapid under these conditions.
