Abstract
The stability constants of complexes of silver(I) with allyl alcohol, prop-2-en-1-ol, trans-but-2-en-1-ol, but-3-en-1-ol, pent-4-en-1-ol, and hex-5-en-1-ol have been determined in a number of solvents. The corresponding enthalpy and entropy changes have been evaluated. The stability constants depend on the solvent in the order propylene carbonate > water > methanol > ethanol [graphic omitted] acetonitrile, which is ascribed to competition between the unsaturated alcohol and the solvent. But-3-en-1-ol shows unexpectedly high stability constants in methanol, ethanol, and propylene carbonate which are ascribed, on the basis of entropy data, to chelate-ring formation; no chelation is obseved in water.Keywords
