摘要:Phosphine compounds represented by the following formula (1): n nwherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 and R 7 represent substituents, and asymmetric synthesis catalysts containing transition metal phosphine complexes with the compounds contained as ligands therein.n n The novel phosphine compounds according to the present invention are useful especially as ligands in transition metal complexes. The transition metal phosphine complexes are useful as catalysts for asymmetric synthetic reactions. The novel phosphine compounds useful as ligands can be prepared by a relatively economical preparation process. Further, use of these catalysts can afford hydrogenated products with high optically purity and is also extremely useful from the industrial standpoint.

标题:Homogeneous process for the ruthenium catalyzed addition of carboxylic acids to alkynes

摘要:The present invention relates to a homogeneous, ruthenium catalyzed liquid phase process for vinyl ester synthesis. It has been found that by adding at least one selectivity enhancer to the reaction system, selectivity to the addition reaction is improved while byproduct formation is inhibited. Useful selectivity enhancers include non-reacting heteroatom containing molecules that are believed to act by weakly coordinating to the ruthenium/phosphine ligand complex.
