Abstract

The second-generation Grubbs analogues (H2IMes)-RuCl 2(=CHPh)(PR3) (R = Me, Bu) were essentially metathesisinactive and air-stable at room temperature but exhibited first-order metathesis with ethyl vinyl ether at elevated temperature. The PMe3 complex underwent second-order ligand exchange with PBu3, indicating different coordination mechanisms (dissociative vs associative) in the two reactions.
