OXIDATION OF SULFIDES TO SULFOXIDES BY 1-ACETYL-v-TRIAZOLOPYRIDINE/HYDROGEN PEROXIDE SYSTEM

Dialkyl, diaryl, and mixed alkyl aryl sulfides are convertd to sulfoxides in high yield by the use of the 1-acetyl-v-triazolopyridine/hydrogen peroxide biphasic system.

Oxidation Studies on β-Lactam Antibiotics. The 6-(Diacylamino)penicillins

The oxidation of the 6-(diacylamino)penicillins is a convenient, high yield route to the penicillin 1α-sulfoxides.The yield of the 1α-sulfoxide is dependent on the solvent, the temperature, the C-3 ester function, and the substituent at the C-2 position.T
