C. Coin et al., Bi-0/O-2 as a new catalytic system for the oxidation of alpha-ketols, alpha-hydroxy acids and epoxides, EUR J ORG C, (4), 2001, pp. 735-740
Bi-0 has been used as a catalyst for the oxidative C-C bond cleavage under
O-2 of alpha -ketols, alpha -hydroxy acids and terminal epoxides, to give t
he corresponding carboxylic acids. The results are compared to those obtain
ed in similar oxidation reactions catalysed by Bi-III carboxylates. These r
eactions constitute the first example of the catalytic use of Bi-0 in oxida
tion reactions, and the first evidence for a Bi-III/Bi-0 redox couple under
molecular oxygen.
