Method for preparing diphenylethanone from benzyl alcohol through photocatalytic one-step method

The present invention relates to a method for preparing diphenylethanone from benzyl alcohol through a photocatalytic one-step method. According to the method, diphenylethanone is directly prepared byusing inexpensive benzyl alcohol as a raw material under the action of a solid photocatalyst; and the reaction process comprises: mixing benzyl alcohol, a catalyst and an acetonitrile solvent are mixed, placing in a pressure container, replacing with an inert gas, and carrying out illumination stirring at a room temperature, wherein the reaction time is more than 1 h, the catalyst is easily separated from the reaction system after the reaction and can be recycled multiple times, and the separation yield of diphenylethanone is up to 81%.

A structureeactivity relationship study on the Wacker oxidation of stilbenes at ambient condition

To evaluate which structural elements of the stilbenes are responsible for their activity on the Wacker oxidation, a series of stilbenes with various functional moieties and substitution patterns were considered. In this regard, it is found that the oxidation rate of stilbenes strongly depends on their structures to give the corresponding carbonyl compounds. Consequently, the ortho position of alkene and methoxy groups plays a key role in the complexation with PdCl2. The oxidation process is clean with high selectivity of product and low percentage of byproducts.
