The first members of a homologous series of long‐chain, multiply unsaturated esters were obtained upon selective ring‐opening metathesis of cyclopentene with methyl acrylate [Eq. (a)]. The catalysts are cationic carbynehydridoruthenium complexes (e.g. L=OEt 2 ), which were prepared for the first time by protonation of hydridovinylideneruthenium compounds in the presence of L.
