An efficient method to oxidize an olefin to the less substituted carbonyl compound is described. This new methodology utilizes borane dimethyl sulfide followed by tetrapropylammonium perruthenate N-methylmorpholine N-oxide to oxidize the resulting alkylborane.
The preparation of α-terpineol by direct hydration of limonene catalyzed by zeolites beta was studied. The same catalyst was used to prepare perillyl alcohol by isomerization of β-pinene oxide in the presence of water. The aim was to optimize the reaction conditions to achieve high conversions of starting material and high selectivity to the desired products. In the case of limonene, it was found that
Myrtenol and myrtanal find their utilization as fine chemicals or intermediates for the synthesis of food additive myrtanol. β-Pinene oxide rearrangement was studied using homogeneous Lewis and Brønsted acids as catalysts for the production of these compounds. The composition of reaction products depended on the type of active sites. Lewis active sites favoured the formation of myrtanal while in presence

Co-Ag supported on the SiO2 catalyst was synthesized by the sol-gel method and characterized using XRD, FT-IR, TG-DTG, BET, CV, and SEM/EDX analysis. The catalytic performance of the resulting catalyst was examined by the oxidation of mono and sesquiterpenic olefinsusing hydrogen peroxide and tert-butyl peroxide as oxidant agents. Various parameters such as catalyst amount, temperature, and solvents
