Carboxylic acids react with terminal alkynes in the presence of a catalytic amount of RuCl x (p-cymene)(triazol-5-ylidene) to selective generate Z-alk-1-en-1-yl esters. The anti-Markovnikov and trans addition on the terminal alkyne gives access to Z-alkene derivatives of phenylacetylene, t-butylacet
