ABSTRACT:
A novel hydroformylation process for the conversion of olefins having up to about 20 carbon atoms to their corresponding aldehydes is provided herein involving the use of catalysts comprising chelates in which a ligand is chelated at a metal center to produce at least one heterocyclic ring with the central metal atom as part of the ring, i.e., platinum-group metal phosphinoalkylsilyl complexes with bis- or tris(phosphinoalkyl)silyl. Novel catalysts are also provided which are platinum-group metal complexes with bis- or tris(phosphinoalkyl)silyl ligands, which are synthesized by using novel bis(phosphinoalkyl)silanes or tris(phosphinoalkyl)silanes.
