Reacting N-aryliminophosphoranes with 1-(het)aroyl-2-aryldiazenes in preheated diphenyl ether at ca. 150-250 °C for 5-25 min affords in most cases the 1,3-diaryl-1,4-dihydrobenzo[e][1,2,4]triazin-4-yls (aka Blatter radicals) in moderate to good yields. Al

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
Thermolysis of polyazapentadienes. Part 10. Flash vacuum pyrolysis of azoalkenes and some azocarbonyl compounds

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.
