Investigations into the hydrogenation of diolefins and prochiral olefins employing the “Daniphos”-type ligands†
Abstract
A number of enantiopure, planar chiral diphosphines of the Daniphos-type have been synthesized in good chemical yields and excellent stereochemical outcome according to a modular, straightforward synthetic method based on an arene–chromium–tricarbonyl scaffold. They were readily converted to their rhodium complexes, two of which have been characterized by
