ABSTRACT OF THE DISCLOSURE A compound having the formula YmXnCC(R1)=C(R2)R3 where Y is hydrogen, cyano or C2-C19 carbalkoxy; X is chlorine or bro- mine; R1 is hydrogen, chlorine, bromine or -COOR4; wherein R4 is C1-C18 alkyl, C3-C18 alkanyl, C5-C6 cycloalkyl, C7-C9 aralkyl or C1-C18 linear or branched alkyl, provided that R1 is not chlorine or bromine if R2 is chlorine or bromine and if R1 and R2 are hy- drogen they must be in the trans configuration; or R1 and R2 together is C3-C10 alkylene; R3 is an electron withdrawing group; n is 1, 2 or 3 and m is 3-n and the making said compound is dis- closed. An intermediate compound, useful in the manufacture of the above compound, having the formula YmXnCCHR1-CR2R3X1 where Y, X, R1, R2, R3, n and m have the meanings given for the com- pound of this invention and where X1 is chlorine or bromine with the limitation that when n is 3, R1 is hydrogen, X and X1 are chlorine, if R2 is methyl then R3 is not methoxycarbonyl and if R2 is hydrogen then R3 is not methylcarbonyl, and a process for making said intermediate is described. A composition incorporating the compound, YmXnCC(R1)=C(R2)R3, with a vanadium catalyst, useful as a cata- lytic agent, is also disclosed. A process for preparing poly(alpha-olefins) employing a com- pound of the above formula as a catalyst without any of the re- strictions relating to the meaning of R1 and R2 is also taught.
