摘要

Abstract Reactions of the bis (pyridine) complex (H 2 IMes)(Py) 2 (Cl) 2 Ru (= CHPh),(H 2 IMes= 1, 3-dimesityl-4, 5-dihydroimidazol-2-ylidene) and the highly fluorophilic phosphines [R fn (CH 2) m] 3 P [1; m/n= a, 2/6; b, 2/8; c, 2/10; d, 3/8; R fn= CF 3 (CF 2) n− 1] give (H 2 IMes){[R fn (CH 2) m] 3 P}(Cl) 2 Ru (= CHPh)(4a–d, 64–78%), which are analogues of Grubbs' second generation alkene metathesis catalyst. Complexes 4a, b are effective ...
