A dinuclear ruthenium catalyst with a confined cavity: Selectivity in the addition of aliphatic carboxylic acids to phenylacetylene

A dinuclear ruthenium catalyst with a rigid anthracene spacer shows excellent regio- and stereo-selectivity in the atom-economic addition of aliphatic carboxylic acids to phenylacetylene, producing exclusively anti-Markovnikov enol-esters with high E/Z ratios of the isomers.

Synthesis and molecular structure of [RuCl{C(=CHPh)OC(=O)CH2CH3}(CO)(PPh3) 2]: A real intermediate in ruthenium complex-catalyzed selective synthesis of a (Z)-enol ester

Reaction of [RuCl(η2-O2CCH2CH3)(CO)(PPh 3)2] (1) and phenylacetylene gives [RuCl{C(=CHPh)OC(=O)CH2CH3}(CO)(PPh3) 2] (2a). The X-ray structure analysis of 2a reveals that it includes a (Z)-enol ester-like 1-propanoyloxy-2-phenylethenyl-C1,O ligand. In the catalytic addition of propanoic acid to phenylacetylene, the complex 2a acts as a real intermediate that gives (Z)-2-phenylethenyl propanoate, selectively. The presence of the free PPh3 in the reaction mixture depresses formation of some dicarbonylruthenium species that catalytically produce (E)- and Markovnikov-type enol esters.
