One pot reaction on epoxidation of α,β-unsaturated ketones and subsequent C C coupling catalyzed by palladacycles

摘要

One pot reaction for epoxidation and Suzuki Miyaura coupling of a number of quinolinyl α,β-unsaturated ketones has been developed by using a predefined palladium(II) catalyst fabricated with 7-diethylamino-2-oxo-2H-chromene Schiff bases. Representative epoxide intermediates were isolated and their structures were established by X-ray crystallography.
