Abstract

The regioselective hydroformylation of methyl 3-pentenoate (M3P) leading to linear 5-formyl methyl pentanoate (3-FMP) was studied. For this purpose Pt/Sn catalyst systems were modified by diphosphine ligands derived from heteroaromatic xanthene-type hydrocarbons. These xantphos ligands possess a large bite angle combined with a rigid backbone. The (P∩ P) PtCl2 catalyst precursor complexes were prepared and characterized by 1H-and ...
