Abstract
Transition metal-diorganophosphite complex catalyzed carbonylation processes, especially hydroformylation, as well as transition metal-diorganophosphite ligand complex compositions, diorganophosphite ligands and transition metal-diorganophosphite catalysts.
Claims5
A diorganophosphite ligand having the general formula ##STR82## wherein Z.sup.2 and Z.sup.3 each individually represent a radical selected from the group consisting of hydroxy and an oxy radical --OR.sup.6, wherein R.sup.6 represents a substituted or unsubstituted monovalent hydrocarbon radical;
- wherein Y.sup.1 and Y.sup.2 each individually represents a radical selected from the group consisting of hydrogen, an alkyl radical having from 1 to 8 carbon atoms, substituted or unsubstituted aryl, alkaryl, aralkyl and alicyclic radicals;
- wherein W represents a substituted or unsubstituted monovalent hydrocarbon radical;
- wherein each y individually has a value of 0 to 1, wherein Q is a divalent bridging group selected from the class consisting of --CR.sup.1 R.sup.2, --O--, --S--, --NR.sup.3 --, --SiR.sup.4 R.sup.5 -- and --CO--, wherein each R.sup.1 and R.sup.2, radical individually represents a radical selected from the group consisting of hydrogen, alkyl of 1 to 12 carbon atoms, phenyl, tolyl and anisyl, wherein each R.sup.3, R.sup.4, and R.sup.5 radical individually represents --H or --CH.sub.3, and wherein n has a value of 0 or 1.
