1,2-Diols have important applications in pesticides, chiral medicines and fine chemicals. A Pd(II)-catalyzed 1,2-diacetoxylation method using readily available acetic acid as the oxygen source and oxygen as the oxidant was developed. For the 1,2-diacetoxylation of conjugated dienes, the reaction proceeds with high 1,2-regioselectivity. This protocol has good substrate scope for conjugated dienes possessing aryl-, ester-and carbonyl groups. The catalytic products can be transformed to 1,2-diols through simple alcoholysis or hydrolysis, therefore it is an efficient method for the synthesis of 1,2-diols.

Key words: palladium, conjugated diene, 1,2-diacetoxylation, 1,2-diol
