delivering strictly linear, low molecular weight PE waxes (between 924 and 5550 g mol−1) of narrow dispersity and terminated with vinyl functionality. By comparison, Co6, possessing a more extended fluorinated para-CH(C6H5)ArF group, was the least active but afforded the highest molecular weight polyethylene (up to 10 027 mol−1). In addition, DFT studies of the model Co(I)-propyl species, Co1′, Co3′
