ABSTRACT:
Novel homogeneous bimetallic hydroformylation catalysts, and processes utilizing these catalysts to convert alkenes, particularly alpha olefins, under mild conditions to a product rich in aldehydes, particularly a product containing a high ratio of linear:branched chain aldehydes. The catalysts can be produced from a binucleating tetratertiaryphosphine ligand capable of strongly coordinating two metal centers and holding them in general proximity to one another. Bimetallic catalyst precursors are produced which, on reaction with carbon monoxide and hydrogen forms the active bimetallic hydroformylation catalyst system.
