A catalyst-free protocol for direct oxidative esterification of alcohols and aldehydes

A fast, simple, and efficient protocol for the direct conversion of alcohols and aldehydes to methyl ester has been developed using TsNBr2 without any catalyst. The one pot reaction proceeds in the presence of a base at room temperature in methanol, to produce the corresponding methyl ester in high yield within a short time. (C) 2014 Elsevier Ltd.
