NEW METHODS AND REAGENTS IN ORGANIC SYNTHESIS. 32. LITHIUM TRIMETHYLSILYLDIAZOMETHANE : A NEW SYNTHON FOR THE PREPARATION OF 1, 2, 3-TRIAZOLES

Abstract

Lithium trimethylsilyldiazomethane, prepared from trimethylsilyldiazomethane and n-butyl lithium, reacts smoothly with various nitriles to give 4-substituted 5-trimethylsilyl-1, 2, 3-triazoles in excellent yields.
