| Abstract
| - The basic ethanolysis of esters and anilides endowed with a distal carboxylate anchoring group iscatalyzed by the dinuclear Ba(II) complexes of cis- and trans-stilbenobis(18-crown-6). Comparisonwith the catalytic efficiency of a mononuclear model catalyst demonstrates that the two metal ionsin the dinuclear complexes act synergically. The cis form of the catalyst is more efficient than thetrans form and much more sensitive to the size of the substrate, showing that the concave shapeimposed by the cis double bond is better suited for catalysis. An experiment in which the less activetrans form is photoactivated in situ is also reported.
