摘要： A NICKEL COMPLEX COMPOUND REPRESENTED BY THE FORMULA:

NI.(2-(A-N=CH-),X-PYRIDINE)

WHEREIN X IS A HYDROGEN ATOM OR A NON-DISSOCIATING SUBSTITUENT SUCH AS METHYL OR CHLORINE AND A IS A GROUP OF THE FORMULA:

-R OR -(CH2)N-N(-R)-R1

IN WHICH R AND R'' ARE EACH A HYDROGEN ATOM, A LOWER ALKYL GROUP, A CYCLO(LOWER) ALKYL GROUP, AN ARYL GROUP OR AN AR(LOWER)ALKYL GROUP AND N IS AN INTEGER OF 2 OR 3, WHICH IS PREPARED BY TREATING AN OLEFIN COORDINATED COMPLEX OF ZERO VALENT NICKEL WITH A SCHIFF BASE OF THE FORMULA:

2-(A-N=CH-),X-PYRIMIDINE

WHEREIN X AND A ARE EACH AS DEFINED ABOVE. THE NICKEL COMPLEX IS USEFUL AS A CATALYST IN OLIGOMERIZATION OF BUTADIENE AND COOLIGOMERIZATION OF THE SAME IN THE PRESENCE OF AN A-OLEFIN WITH A HIGH SELECTIVITY.
