N-functionalized benzotriazole-1-carboximidoyl chlorides: synthetic equivalents for isocyanide dichlorides.
Readily prepared N-functionalized benzotriazole-1-carboximidoyl chlorides are proposed as stable and novel isocyanide dichloride synthetic equivalents. Subsequent condensations of these new intermediates afford polysubstituted guanidines, S-aryl isothioureas, and 2-aminoquinazolin-4-thiones.
