New catalyst for the dimerization of diolefins

Claim 1

A PROCESS FOR THE DIMERIZATION OF DIOLEFINS OF UP TO ABOUT 10 CARBON ATOMS IN LIQUID PHASE WHICH COMPRISES CONTACTING SAID DIOLEFIN IN SOLUTION IN AN INERT SOLVENT AT A TEMPERATURE BETWEEN 0*-100*C,. WITH A DIMERIZATION CATALYTIC AMOUNT OF UP TO ABOUT 1 WEIGHT PERCENT OF A CATALYST WHICH IS THE INTERACTION PRODUCTION OF A FIRST AND A SECOND METALLIC COMPLEX, EACH OF SAID COMPLEXES CONTAINING AT LEAST ONE OF NITROSLY AND CARBONYL LIGANDS AND SAID INTERACTION PRODUCT CONTAINING AT LEAST ONE NITROSYL GROUP, WHEREIN SAID FIRST METALLIC COMPLEX IS A SODIUM N-CARBONYL-P-NITROSYL METALLATE OF THE FORMULA NAM(M1(CO)N(NO)P), IN WHICH M1 IS A TRANSITION METAL OF GROUP VB, VIB, VIIB OR VIII OF THE PERIODIC TABLE, N AND P ARE INTEGERS OF 0-5,, THE SUM OF N + P IS 1-6, AND M IS AN INTEGER OF 1-5, AND WHEREIN SAID SECOND METALLIC COMPLEX IS A R-CARBONYL-S-NITROSYL HALIDE OF THE FORMULA XQ(M2(CO)R(NO)S) IN WHICH M2 IS A TRANSITION METAL OF GROUPS VB, VIB, VIIB OR VIII OF THE PERIODIC TABLE, X IS HALOGEN, CYANIDE, SULFOCYANIDE, ISOCYANATE, NITRATE, NITRITE, SULFATE, ACETYLACATONATE OR CARBOXYLATE, R AND S ARE INTEGERS OF 0-5, Q IS AN INTEGER OF 1-5, THE SUM OF R + S IS 1-6, AND WHEREIN P AND S ARE NOT SIMULTANEOUSLY 0.
