A new and efficient Ag‐catalyzed method for the nitration of anilides by using sodium nitrite as a cheap and available NO2 source has been developed. This C–H functionalization reaction is ortho‐selective, achieves moderate to high yields and shows excellent functional group tolerance. Furthermore, it provides a novel approach to ortho‐nitrated anilides, which are very tricky to access with traditional methods.
A RuII‐catalyzed highly regioselective C–H acyloxylation of azoarenes with inexpensive alkyl and aryl carboxylic acids as an acyloxylation agent is described. The reaction demonstrates a broad substrate scope and good functional group tolerance. This method provides a facile procedure to synthesize ortho‐acyloxylated azoarene derivatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
