The dimeric bis(allyl)ruthenium(IV) complex [{RuCl(μ-Cl)( η3:η3-C10H16)}2] (C10H16 = 2,7-dimethylocta-2,6-diene-1,8-diyl) (5) and several mononuclear species trans-[RuCl2(η3: η3-C10H16)(L)] (L = two-electron-donor ligand) (6) derived from 5 have been checked as catalysts for the addition of carboxylic acids onto terminal alkynes using water as a green reaction medium. The best results in terms of activity and regioselectivity were obtained with the mononuclear derivative trans-[RuCl2(η3: η3-C10H16)(PPh3)] (6a), which was able to promote the selective Markovnikov addition of both aromatic and aliphatic carboxylic acids to a large variety of terminal alkynes, enynes, and diynes as well as propargylic alcohols. In this way, a wide number of enol esters and β-oxo esters could be synthesized in moderate to good yields under mild conditions (60 °C) in an aqueous medium.

New (Ph2P(CH2)nPPh2)Ru( 2-methylpropenyl)2 complexes have been prepared and their catalytic activity has made possible the regioselective anti-Markovnikov and stereoselective Jrans-addition

2-Acyloxy-1,3-dienes are obtained by regioselective addition of carboxylic acids and N-protected amino acids to vinylacetylene derivatives, with (arene)(phosphine)ruthenium(II) complexes as catalysts.
