Developing well-defined iron-based catalysts for olefin metathesis would be a breakthrough achievement in the field not only to replace existing catalysts by inexpensive metals but also to attain a new reactivity taking advantage of the unique electronic structure of the base metals. Here, we present a two-coordinate homoleptic iron complex, Fe(HMTO)2 [HMTO=O-2,6-(2,4,6-Me3C6H2)2C6H3], that is capable of performing ring-opening metathesis polymerization of norbornene to produce highly stereoregular polynorbornene (99% cis, syndiotactic). The use of heteroleptic Fe(HMTO)(RO) [RO=(CH3)2CF3CO, CH3(CF3)2CO, or Ph(CF3)2CO] prepared in situ significantly increases the polymerization rate while preserving selectivity. The resulting polymers were characterized by 1H and 13C NMR spectroscopy and gel-permeation chromatog.
