| Research Abstract |
1,3-Diketones and ketoesters, called as active methylene compounds or active methane compounds, are extremely useful synthetic intermediate in synthetic organic chemistry. The straightforward synthetic method of these compounds from easily available compounds is interesting on synthetic organic chemistry. We found that the methylene group at the beta position of ketones and nitriles are oxidized into carbonyl by palladium-catalyzed oxidative amination of saturated carbonyl derivatives, such as ketones and nitriles, followed by one-pot hydrolysis with hydrochloric acid. The sequential reaction was conducted as one-pot process. Thus, a variety of 1,3-diketones and beta-cyanoaldehyde can be easily obtained from simple alkyl ketones or saturated nitriles.
