Abstract: A microencapsulated catalyst is prepared by dissolving or dispersing a catalyst in a first phase (for example an organic phase), dispersing the first phase in a second, continuous phase (for example an aqueous phase) to form an emulsion, reacting one or more microcapsule wall-forming materials at the interface between the dispersed first phase and the continuous second phase to form a microcapsule polymer shell encapsulating the dispersed first phase core and optionally recovering the microcapsules from the continuous phase. The catalyst is preferably a transition metal catalyst and the encapsulated catalyst may be used for conventional catalysed reactions. The encapsulated catalyst may recovered from the reaction medium and re-cycled.

Abstract: A catalyst for synthesis reaction that can allow the cross coupling reaction at an improved yield, and yet can be collected after used for the reaction and recycled, and a synthesizing method for a compound using the same catalyst for synthesis reaction.

Abstract: There is provided processes for metal mediated reactions, particularly cross coupling and carbometallation reactions, wherein the metal is present as a catalyst system comprising a catalyst microencapsulated within a permeable polymer microcapsule shell and the reaction is carried out under super-critical or near super-critical conditions. Preferred metal-mediated cross coupling reactions include Heck, Suzuki, Sonogashira and Stille reactions. Preferred carbometallation reactions include hydroformylations.
