METALORGANIC CATALYSTS FOR CHEMO-, REGIO- AND STEREOSELECTIVE REACTIONS, AND CORRESPONDING PRECURSORS

摘要

Metallic catalysts of the general formula (I) and their precursors, suitable for chemo- regio- and stereoselective reactions, derived from ortho- bis(1-phospholanyl)-heteroarenes. The new catalysts are characterized by the presence of two homomorphic phospholanic rings set in adjacent positions of an aromatic pentatomic heterocycle.
