A convenient methodology for synthesizing amide, hydroxamate, and ester using Oxyma and thionyl chloride is described here. A total of 32 examples, 19 amides, six hydroxamates, and seven esters, are reported with a 67 to 86 % yield. Recyclability and racemization suppression are the crucial features of this protocol. A detailed NMR-based mechanistic study indicates the possibility of forming two novel intermediates, Oxyma sulfinyl chloride and sulfinyl diOxyma, during the process.
