Synthesis and molecular structure of vanadium(III) dithiolate complexes: a new class of alkene polymerization catalysts

The synthesis and catalytic activity in ethylene polymerization of new vanadium complexes of 2,2′-oxydiethanethiolate [O(CH2CH2S)22–] are described; the complexes [V(µ-DIPP)2{O(CH2CH2S)2}Li(MeCN)2] and [V(DIPP){O(CH2CH2S)2}(py)] [DIPP = (OC6H3Pri2-2,6)–] have been structurally characterized.
