Palladium-catalyzed oxidation of monoterpenes: novel tandem oxidative coupling-oxidation of camphene by dioxygen

Palladium-catalyzed oxidation of monoterpenes: novel tandem oxidative coupling-oxidation of camphene by dioxygen. da Silva, Marcio J.; Gusevskaya, Elena V. (Departamento de Quimica-ICEx, Universidade Federal de Minas Gerais, Belo Horizonte, MG 31270-901, Brazil). Journal of Molecular Catalysis A: Chemical, 176(1-2), 23-27 (English) 2001 Elsevier Science B.V. CODEN: JMCCF2. ISSN: 1381-1169. DOCUMENT TYPE: Journal CA Section: 30 (Terpenes and Terpenoids) The Pd-catalyzed stereoselective oxidative coupling of (-)-camphene gives mainly (E,E)-diene, i.e., bis(3,3-dimethyl-2-norbornylidene)ethane, which can be oxidized into the corresponding a,b-unsatd. ketone, i.e. (3,3-dimethyl-2-norbornyl)(8-camphenyl)ketone, with LiNO3 being used as a reoxidant and dioxygen as a final oxidant; these two reactions are performed in a one-pot process with up to 90% selectivity for ketone. The applications of the Pd(II)/NO3- catalytic system to the oxidn. of limonene and b-pinene have also been studied.
