Abstract

Abstract The solubility of the modifying ligand is an important parameter for the efficiency of a rhodium-catalysed hydroformylation system. A facile synthetic procedure for the preparation of well-defined xanthene-type ligands was developed in order to study the influence of alkyl substituents at the 2-, and 7-positions of the 9, 9-dimethylxanthene backbone and at the 2-, and 8-positions of the phenoxaphosphino moiety of ligands 1–16 ...
