Reusable rhodium catalyst for the selective transvinylation of sp2-C linked carboxylic acid

The vinyl benzoate derivatives were successfully synthesized by the transvinylation reactions that vinyl group transferred from vinyl acetate to aromatic carboxylic acids with the recoverable catalyst RhCl3·3H2O. This catalyst features air stable and tolerance of water, good reusable ability, meanwhile, shows high selectivity for aromatic carboxylic acid in the presence of phenolic hydroxyl. With this method, a variety of vinyl benzoate derivatives can be produced with up to 95% yield.

METHOD FOR PRODUCING CYCLIC UNSATURATED COMPOUND

The present invention provides a method for producing a cyclic unsaturated compound, which sufficiently suppresses generation of acyclic unsaturated compounds and permits excellent yield and reaction rate. Such a method for producing a cyclic unsaturated compound is a method for producing a cyclic unsaturated compound by reacting an a, ?-unsaturated carboxylic acid with an unsaturated organic compound, wherein the method comprises a step of reacting the a, ?-unsaturated carboxylic acid with the unsaturated organic compound in the presence of a catalyst.
