In a mild and efficient oxidative esterification using TCCA as the oxidant, aromatic and aliphatic aldehydes are converted in situ into their corresponding acyl chlorides, which are then reacted with primary and secondary aliphatic, benzylic, allylic, and propargylic alcohols and phenols to give various esters in high yields.
