Novel ligand-metal complex, useful for hydroformylation of ethylenically unsaturated compounds, comprises ruthenium, rhodium, palladium and platinum and a monophosphine, monophosphinite or monophosphinamidite ligand

摘要

A novel ligand-metal complex comprises ruthenium, rhodium, palladium and platinum and a monophosphine, monophosphinite or monophosphinamidite ligand. A ligand-metal complex (I) comprises ruthenium, rhodium, palladium and platinum and a monophosphine, monophosphinite or monophosphinamidite ligand of formula (1). An Independent claim is included for the hydroformylation of ethylenically unsaturated compounds by reaction of at least one ethylenically unsaturated compound with carbon monoxide and hydrogen in the presence of a ligand-metal complex (I). A = together with the phosphorous atom it is bonded to comprises a 2-phospha-tricyclo(3.3.1.1(3,7)) decyl group, optionally having non-neighboring carbon atoms substituted by oxygen atoms and optionally substituted; R1 = hydrogen or an organic group bonded via carbon, oxygen or nitrogen and having a mol. wt. of up to 20,000.
