Water soluble metal complexes and catalysts: Part XI. Novel ligands from tris(hydroxymethyl)phosphane and amino acids: Synthesis and catalytic studies in two phase hydroformylation
Novel water soluble ligands were prepared in high yields by condensation of various amino acids with tris(hydroxymethyl)phosphane. Rhodium complexes of these ligands, formed in situ, were tested in two phase hydroformylation of propylene. Selectivity observed with these ligand systems is easily controlled by altering the pH of the reaction mixture.
