摘要：
Ethylene is selectively dimerized into butenes by the action of Ni(MeCN)6(BF4)2 1 and alkylaluminum compounds (AlEt3 or AlEt2Cl). Under homogeneous phase reaction conditions, this system shows high activity (TOR = 2 451 h-1) and selectivity to C4 products (97%) under mild conditions (10 bar, 50-degrees-C). Anchoring 1 on Amberlyst-15 resin strongly increases the selectivity for but-1-ene (up to 96%).
