The influence of diverse carboxylic acid on the preparation of chlorohydrin esters using a one-pot esterification-chlorination reaction, in which one of the reagents (chlorotrimethylsilane) acts as solvent, is described. Whereas the acid with low pKa provided higher amounts of the 2-chloro regioisomer, the ones with higher pKa rendered the 1-chloro regioisomer in 80% yield. These results are in accordance with the mechanism proposed in a previous article.
