One aspect of the present invention relates to novel ligands for transition metals. A second aspect of the present invention relates to the use of catalysts comprising these ligands in transition metal-catalyzed carbon-heteroatom and carbon-carbon bond-forming reactions. The subject processes provide improvements in many features of the transition metal-catalyzed reactions, including the range of suitable substrates, reaction conditions, and efficiency.
Disclosed is a composition comprising (A) at least one compound selected from the group consisting of an ether compound having two or more ether groups, a trivalent phosphorus compound, and a ketone compound, (B) a boron trihalide, and (C) an episulfide compound.
