Homogeneous tandem catalysis involving a highly selective, aluminoxane-activated bis (2- decylthioethyl) amine⊙ CrCl3 complex for the synthesis of 1-hexene in tandem with a number of metallocene catalysts is discussed. Analysis by means of DSC, CRYSTAF, HT- GPC, 13C NMR, and FTIR suggests that copolymers of 1-hexene and ethylene are produced with significant selectivity toward 1-hexene as comonomer. The selectivity of 1- ...
