Patent ID: 7524992

Claim:
A process for creating a carbon-carbon bond by coupling a transferable group to an acceptor group comprising the steps of: a) activating a siliceous compound comprising a group which can be transferred by an activating agent; b) adding a derivative carrying an acceptor group and, simultaneously or consecutively, in any order; and c) adding a compound of palladacycle type which acts as a catalyst of the reaction of coupling the transferable group to the acceptor group by creation of said carbon-carbon bond, in which the siliceous compound carrying a transferable group is a dihalosilane of formula (I): where: X 1 and X 2 , which are identical or different, are, independently of one another, a halogen atom selected from fluorine, chlorine, bromine and iodine; R T is the transferable group and is selected from an aryl, vinyl and allyl radical, wherein said radical may optionally be substituted; and R is selected from the hydrogen atom, the R T radical defined above, and a linear or branched alkyl radical comprising from 1 to 6 carbon atoms; wherein said process is performed without the use of a phosphine.
