Novel tridentate phosphines and method of forming aldehyde hydrogenation catalysts
-
Page/Page column 9, (2008/06/13)
This invention comprises a process for hydrogenation of aldehydes to alcohols using novel homogeneous catalysts. The catalysts are generated in situ under hydrogen and carbon monoxide gases in a suitable solvent, by mixing a rhodium catalyst precursor, such as Rh(CO)2 acetoacetonate and a defined ligand.

Addition of phenylphosphine to allylphosphonate followed by reduction of the resulting diphosphonate gives a new branched phosphine, bis(3-phosphinopropyl)phenylphosphine. Its reaction with paraform and p-toluidine yields oligomeric 3-[3-(propylenophenylphosphino)propyl]-1,5-di-p-tolyl-1,5,3, 7-diazadiphosphacyclooctane. Diethyl (5-allyl-2-ethoxybenzyl)phosphonate was obtained. Its reduction gives unsaturated (5-allyl-2-ethoxybenzyl)phosphine. This product adds two moles of formaldehyde to give bis-(hydroxymethyl)(5-allyl-2-ethoxybenzyl)phosphine. The reaction of this compound with p-toluidine yielded, depending on the conditions, the corresponding bis(aminomethyl)phosphine, 1,3,5-diazaphosphorinane, and 1,5,3,7-diazadiphosphacyclooctane, and also their derivatives containing allyl substituents.

The title triphosphaalkanes (n = 0 - 2; R, R' = Me, Ph) (3a - d) were synthesized via free radical addition of primary or disecondary phosphanes to the allyl group of the esters R'P(O)(OiPr)CH2CH=CH2 and subsequent LiAlH4 reduction of the products thus ob
