The alkenyl derivatives <(C6Me6)(PMe3)ClRu-C(OMe)=CHR> IIIa (R=Me) and IIIb (R=Ph) have been prepared by deprotonation of the corresponding carbene complexes <(C6Me6)(PMe3)ClRu=C(OMe)CH2R> II with Me3COK.Complexes III can be used as efficient catalysts for the addition of functional carboxylic acids to terminal alkynes to give dioxolanone 4, from R(-)mandelic acid, or methacrylates of the CH2=C(Me)CO-OY: Y=C(=CH2)n-Bu, 6, CH2CH2C<*>CH, 8, or C(=CH2)CH2CH2CH2CH2C(=CH2)OCOC(Me)=CH2, 10.Keywords: Arene complexes; Alkenyl complexes; Ruthenium; Methacrylate monomers; Synthesis
