✦ Synopsis

The alkenyl complexes [Ru{(E)-C(CO 2 Me)=C(H)R}(η 5 -C 9 H 7 ){κ 2 -P,P-(S)-peap}] [R = CO 2 Me (3), H (4)], [Ru{(E)-CH= C(H)Ph}(η 5 -C 9 H 7 ){κ 2 -P,P-(S)-peap}] (5) have been prepared by reaction of the hydride complex [RuH(η 5 -C 9 H 7 ){κ 2 -P,P-(S)-peap}] (2) [(S)-peap = (-)-(S)-N,N-bis(diphenylphosphanyl)(1-phenylethyl)amine] with an equimolar amount of dimethyl acetylenedicarboxylate, or with an excess of the terminal alkynes methyl propiolate or phenylacetylene. Similarly, vinylalkenyl complexes 6a-d have been synthesized by the regio-and stereoselective reaction of the hydride complex 2 with 1-ethynylcycloalkynols. Protonation of the vinyl- [a
