Bronsted bases of widely varying strength are shown to decompose the metathesis-active Ru intermediates formed by the second-generation Hoveyda and Grubbs catalysts. Major products, in addition to propenes, are base·HCl and olefin-bound, cyclometala

The σ-alkyl species RuCl2(CH2PCy3)(py)3 (3a) is intercepted on adding pyridine to the first-generation Grubbs catalyst 1a during RCM or to the isolated resting-state species RuCl2(PCy3)2(═CH2) (2a). Complex 3a is formed by pyridine-induced displac
