Abstract
Valuable fully substituted 1,2,4-triazoles are obtained via a gold-catalyzed three-component reaction involving ethyl diazoacetate, aryldiazonium salts, and nitriles. The reaction proceeds under mild conditions, is regioselective, and allows the introduction of mono- and di-substituted aryl rings at the ortho, meta, and para positions. Mechanistic evidence suggests the participation of Au(III) species as the active catalysts.
期刊介绍：
Tetrahedron publishes full accounts of research having outstanding significance in the broad field of organic chemistry and its related disciplines, such as organic materials and bio-organic chemistry.
Regular papers in Tetrahedron are expected to represent detailed accounts of an original study having substantially greater scope and details than that found in a communication, as published in Tetrahedron Letters.
Tetrahedron also publishes thematic collections of papers as special issues and ''Reports'', commissioned in-depth reviews providing a comprehensive overview of a research area.
