    摘要: Tantalum catalysts or catalyst precursors of the formula ##STR1## wherein X is a halide, or alkoxide and L is an alkene (CH.sub.2 .dbd.CHR) having from 2 to 20 carbon atoms, react with 1-olefins to give catalysts of the formula ##STR2## wherein R.sup.2 is hydrogen or a C.sub.1 to C.sub.18 alkyl such as methyl, ethyl, or propyl. The catalysts or catalyst precursors selectively dimerize 1-olefins to the two possible disubstituted .alpha.-olefin dimers, the ratio of which depends on the nature of R.

    摘要: Olefines such as mono-olefines and diolefines or mixtures thereof may be oligomerized using p -allyl metal compounds or p -allyl metal halides wherein the metal is a transition metal of Groups IV-VIII. Lewis acids such as organoaluminium compounds and aluminium halides, and Lewis bases such as (a) the alkyl, cycloalkyl, aralkyl or aryl compounds of elements of Group V other than nitrogen, (b) the tri-alkyl, -cycloalkyl, -aralkyl or -aryl esters of elements of Group V other than nitrogen, as well as their triamides and (e) dialkyl sulphoxides may be added. In the examples, butadiene, ethylene, propylene and butene-2 are separately oligomerized, mostly to dimers; also butene-2 and ethylene; ethylene and propylene; and ethylene and cyclohexene are codimerized.ALSO:Olefines such as mono-olefines and diolefines may be polymerized using p -allyl metal compounds or p -allyl metal halides wherein the metal is from Group IVa to VIIa or VIII of the specified Periodic System.
