The synthesis of W(NAr′)(NHC)(=CHR)(2,5-Me2pyr)2 (1; Ar′: 2,6-iPr2C6H3; NHC: 1,3-diisopropylimidazol-2-ylidene; 2,5-Me2pyr: 2,5-dimethylpyrrolide; R: CMe2Ph), W(NAr′)(NHC)(=CHR)(2,5-Me2pyr)(OC6F5) (2), W(NAr′)(NHC)(=CHR)(OSiPh3)2 (3), [W(NAr′)(NHC)(=CHR)(OSiPh3))(MeCN)+][B(ArF)4 ?] (4; B(ArF)4 ?: B(3,5-(CF3)2C6H3)4 ?), [W(NAr′)(NHC)(=CHR)(2,5-Me2pyr))+][B(ArF)4 ?] (5), [W(NAr′)(NHC)(=CHR)(OC6F5))(tBuCN)+][B(ArF)4 ?] (6), W(NAr′)(NHC)(=CHR)(OtBu)2 (7), [W(NAr′)(NHC)(=CHR)(OtBu)+][B(ArF)4 ?] (8), and W(NAr′)(NHC)(=CHR)(OCMe(CF3)2)2 (9) is described, and the reactivity of the complexes in olefin metathesis and cyclopolymerization is reported. The cationic complexes 4, 5, and 6 showed high productivity and activity in olefin metathesis reactions, with turnover numbers of up to 40 000 and turnover frequencies (TOF5min) of up to 31 s?1, and also substantial functional group tolerance toward esters, nitriles, alcohols, and sulfides, particularly in the cyclopolymerization of α,ω-diynes.
