Abstract

Abstract An efficient metal-free oxidative esterification of benzyl C [BOND] H bonds was developed. Using tetrabutylammonium iodide as catalyst and tert-butyl hydroperoxide as co- oxidant, benzylic substrates could react smoothly with various carboxylic acids to give the esters with good to excellent yields. The method was also suitable for the O-protection of N- Boc amino acids. The reaction mechanism was primarily investigated and a radical ...
