Abstract:
A hydroformylation process which comprises reacting an olefin in the presence of an aryl diphosphine-metal complex at an operating temperature from about -80.degree. C. or less to about 500.degree. C. or greater, said catalyst selected from the group consisting of ##STR22## wherein (a) X and Y are each independently selected from the group consisting of alkyl C.sub.1 -C.sub.20, alkenyl C.sub.1 -C.sub.20, alkynyl C.sub.1 -C.sub.20, phenyl, napthyl, --NR--, (where R is H, alkyl C.sub.1 -C.sub.20, phenyl) oxygen and sulfur; (b) m and m' are each separate integers of 0 or 1; (c) R.sub.1 -R.sub.8 are each independently selected from the group consisting of hydrogen, halogen, nitro, amino, alkyl C.sub.1 -C.sub.20, alkoxy, hydroxy-C(O)--OR, --CN, --SO.sub.3 M, --N(R).sub.3 X (where X is a halide), and aryl; (d) R.sub.1 and R.sub.2, R.sub.2 and R.sub.3, R.sub.3 and R.sub.4, R.sub.5 and R.sub.6, R.sub.6 and R.sub.7, R.sub.7 and R.sub.8 may also (in addition to the above) form a cyclic ring containing a total of 2 to 6 atoms selected from the group consisting of carbon atoms, oxygen atoms, nitrogen atoms, sulfur atoms, and mixtures thereof, with the proviso that said ring can be substituted or unsubstituted; (e) R.sub.9 -R.sub.12 and R.sub.14 -R.sub.18, are each independently selected from the group consisting of hydrogen, halogen, --SO.sub.3 M where M is selected from the group of alkali metal, alkaline earth metals, and N(R).sub.4 (where R is H, alkyl C.sub.1 -C.sub.20, Phenyl), alkyl C.sub.1 -C.sub.20, --CO.sub.2 M, N(R).sub.3 X (where X is a halide), --CN, --OR, --C(O)--OR, and --P(R).sub.2, where R is H, alkyl C.sub.1 -C.sub.20, and phenyl; (f) R.sub.13 is selected from the group consisting of a straight chain or branched chain alkyl C.sub.1 -C.sub.20, alkenyl C.sub.1 -C.sub.20, phenyl, napthyl, antracyl, and substituted phenyl, naphthyl, and anthryl; and (g) n is an integer from 0 to 20; (h) M' is selected from the group consisting of manganese, cobalt, nickel, chromium, iron, rhenium, ruthenium, rhodium, technetium, palladium, platinum, osmium, copper, cadmium, indium, tungsten, molybdenium, mercury, gold and silver; (i) L is a ligand which can be bound to M'; and (j) X is an integer of 0 to 7; (k) R.sub.19 is selected from the group consisting of alkyl C.sub.1 -C.sub.20 (straight or branched chain), phenyl (substituted or unsubstituted), and naphthyl (substituted or unsubstituted); and (l) X' is a halide or tosylate and wherein at least one or R.sub.1 -R.sub.12 and R.sub.14 -R.sub.18 is --SO.sub.3 M and wherein the --SO.sub.3 M free catalyst (I), (II), (III), (IV) or (V) is subjected to acid sulfonation and base conditions in order to introduce the at least one --SO.sub.3 M group.
