Abstract

A series of easily accessible diphosphane compounds 14, based on bisphenol A derived backbones, has been prepared. A straightforward two-step synthetic route has been employed to obtain these new ligands in good yields from cheap starting materials. Molecular structures for both compound 2 and its oxidized form (H2O) have been determined and are discussed in detail. The coordination of ligand 2 to palladium, platinum, and rhodium precursors has been studied by NMR spectroscopy as well as X-ray crystallography. The molecular structures of the face-to-face dimeric species [{PdCl(CH3)(2)}2] (6), [{PtCl2(2)}2] (7), and [{RhCl(CO)(2)}2] (8) are described in detail. (© Wiley-VCH Verlag GmbH & Co.
