Abstract
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 homo-morphic phospholanic rings set in adjacent positions of an aromatic pentatomic heterocycle
