Abstract
Borane-tetrahydrofuran complex or borane-methyl sulfide complex is used to generate triacyloxyboranes, which can be effectively reacted with various nucleophiles (alkylamines, arylamines, hydrazides, alcohols, phenols) at reflux in toluene to provide the corresponding amides and esters in excellent yield.
