Abstract

This article summarizes the results of our recent studies on palladium catalytic systems for the oxidation of alcohols and ­alkenes using molecular oxygen or air together with several successful attempts to make the system recyclable from the viewpoint of ‘green and sustainable chemistry’. In addition, palladium-catalyzed novel organic transformations of tert-alcohols (mainly cyclo­butanols) and cyclobutanone oximes are also presented, where β-carbon elimination involving C-C bond cleavage is a key step, ­together with some of their asymmetric versions.
