Cobalt(II) Porphyrin-Catalyzed Oxidation of Olefins to Ketones with Molecular Oxygen and Triethylsilane in 2-Propanol

Matsushita, Yoh-ichi,Matsui, Takanao,Sugamoto, Kazuhiro

, p. 1381 - 1384 (2007/10/02)

An efficient conversion of olefins to ketones was achieved by the use of molecular oxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) complex of porphyrin.The oxidation was accelerated remarkably in alcohols and had chomoselectivity for conjugated olefins.
