Hydrodeoxygenation (HDO) processes have been developed to remove the oxygenated compounds in lipids. However, the HDO process consumes excess hydrogen. As opposed to the HDO process, decarboxylation does not require hydrogen. In this study, decarboxylation of oleic acid without hydrogen was carried out over unsupported CoMo catalysts. Unsupported CoMo catalysts were prepared by a co-precipitation method. The Co/Mo ratio was systematically varied to optimize unsupported CoMo catalyst. The catalyst properties were studied using various characterization techniques and related to the activity results in decarboxylation.

Abstract Methods for generating tert-alkyl organoboron species are in high demand as they are invaluable intermediates for the synthesis of quaternary carbon centres. Herein we report investigations into generation of tert-alkyl organoboron species using imidoyl chlorides as reagents in the organoboron cyanidation reaction. Although alkenyl side-products predominate in particularly hindered cases, tert-alkyl organoboron species can be successfully generated for less hindered examples.
