Conversion of bicyclic C-azoaziridines to 2-substituted 2H-1,2,3-triazoles

In an acidified chloroform solution, bicyclic C-azo-N-(N-hetaryl)aziridines are converted to bicyclic 2H-1,2,3-triazoles. This transformation can occur on the surface of silica gel, and also during storage of these compounds at room temperature. 2005 Spri

Electroluminescent Metal Complexes With Triazoles

Disclosed are electroluminescent metal complexes with triazoles of the formula (I), where n1 is an integer of 1 to 3, m1 and m2 each are an integer 0, 1 or 2, M1 is a metal with an atomic weight of greater than 40, L1 is a monodentat

Oxidative addition of N-aminophthalimide and 3-amino-2-methylquinazolin- 4(3H)-one to conjugated azocyclopentenes and azocyclohexenes

The oxidation of N-aminophthalimide and 3-amino-2-methylquinazolin-4(3H)- one in the presence of conjugated azocyclopentenes, azocyclohexenes, and 3-arylazocyclohexen-2-ones gives adducts at the carbon-carbon double bond corresponding to C-azoaziridines a

A new synthesis of aryl isothiocyanates: Carbon disulfide as a dipolarophile. The reaction of (4,5,6,7-tetrahydro-2H-1,2,3-benzotriazolium-1-yl)arylaminide 1,3-dipoles with carbon disulfide: Synthesis, kinetics, mechanism. Azolium 1,3-dipoles

A new synthesis of aryl isothiocyanates in which the aryl nitrogen moiety ultimately comes from an arylhydrazine is described. Treatment of (4,5,6,7-tetrahydro-2H-1,2,3-benzotriazolium-1-yl)arylaminide 1,3-dipoles (derived from cyclohexane-1,2-dione bis(arylhydrazones)) with carbon disulfide in acetone at ambient temperatures gives high yields of aryl isothiocyanates and 2-aryl-4,5,6,7-tetrahydro-2H-1,2,3-benzotriazole as a leaving group. The kinetics and mechanism of the reaction were investigated. The mechanism involves a polar cycloaddition of the triazolium-aminide to the CS2 generating a partially ring-closed intermediate which fragments to the aryl isothiocyanate. Carbon disulfide is not a kinetic superdipolarophile with (1,2,3-benzotriazolium-1-yl)aminide 1,3-dipoles. The Royal Society of Chemistry 2000.
