Synthesis of azides
WebAug 3, 2011 · Sulfamoyl azides are readily generated from secondary amines and a novel sulfonyl azide transfer agent, 2,3-dimethyl-1H-imidazolium triflate. They react with alkynes in the presence of a CuTC catalyst forming 1-sulfamoyl-1,2,3-triazoles. The latter are shelf-stable progenitors of rhodium azavinyl carbenes, versatile reactive intermediates that, … WebDec 15, 2024 · A method for the metal-free synthesis of benzotriazoles in flow is reported. Using azides and in situ generated arynes, benzotriazoles are formed in a [3+2] cycloaddition within minutes. Employing different substitution patterns of the azide and aryne coupling partners, a modular access to benzotriazoles is provided.
