A novel [3 + 2] cycloaddition between nitrile ylides and diazonium salts was well-established. This copper-catalyzed three-component reaction was distinguished by mild conditions, ready availability, and operational simplicity, thus opening access to 1,2,4-triazoles with a diverse set of substitution patterns.
在腈和重氮盐之间建立新颖的[3 + 2]环加成反应已广为人知。这种铜催化的三组分反应的特点是条件温和,易得性和操作简便性,从而使获得具有多种取代方式的1,2,4-三唑成为可能。
