Cu(I)‐Catalyzed Silylation and Germylation of Azauracils

Abstract

The current study demonstrates a Cu(I) catalyzed direct C(sp2)‐H silylation and germylation of azauracil using triphenylsilane and triphenylgermane. A broad scope, excellent functional group tolerance, and suitability for large‐scale reactions are exhibited in this protocol. Moreover, this method can be readily applied to structurally complex bioactive molecules. Experimental results suggest a radical mechanistic pathway for the reaction.
