报道了一系列具有三齿“SNS”配体双（癸基硫乙基）胺和双（乙硫基乙基）胺的钼配合物的合成、结构和催化研究。具有一系列钼氧化态{(0)、(III)和(IV)}的络合物已经从易于合成的起始材料中以高产率合成获得。还报道了意想不到的二聚钼（I）结构的形成。在可能的情况下，络合物已转化为弱配位四(全氟叔丁氧基)铝酸根阴离子的盐。已经用多种铝助催化剂筛选了配合物的乙烯低聚活性。
Synthetic, structural, and catalytic studies of a series of molybdenum complexes with the tridentate “SNS” ligands bis(decylthioethyl)amine and bis(ethylthioethyl)amine are reported. Complexes with a range of molybdenum oxidation states {(0), (III), and (IV)} have been accessed synthetically in high yields from readily synthesized starting materials. The formation of an unexpected dimeric molybdenum(I) structure is also reported. Where possible, the complexes have been converted to salts of the weakly coordinating tetrakis(perfluoro-tert-butoxy)aluminate anion. The complexes have been screened for ethylene oligomerization activity with a number of aluminum cocatalysts.
