摘要：
A PROCESS FOR THE CATALYTIC DIMERISATION OF 1,3-DIOLEFINES IS DISCLOSED. PREFERRED DIOLEFINES ARE BUTADIENE, ISOPRENE AND PIPERYLENE. THE CATALYSTS USED ARE ONES FORMED BY MIXING A REDUCIBLE NICKEL COMPOUND AND A METAL HAVING A REDUCING ACTION WITH RESPECT TO THE REDUCIBLE NICKEL COMPOUND OR A HALOGEN-FREE ORGANOMETALLIC COMPOUND, OF WHICH METAL ALKYLS, METAL ARYLS OR METAL HYDRIDES ARE EXAMPLES, AND AN ELECTRON DONOR. THEY MAY ALSO BE FORMED BY MIXING A NICKEL COMPLEX COMPOUND WHICH CONTAINS O-VALENT NICKEL WITH AN ELECTRON DONOR. THE ELECTRON DONOR MAY BE AN ESTER OF A PHOSPHOROUS ACID OR A DIOLEFINE. THE PROCESS IS CARRIED OUT WITH INCOMPLETE CONVERSION OF THE 1,3-DIOLEFINE.
