Abstract
The chiral silver complex (trifluoroacetylcamphorato)silver (2) has been prepared and its interaction with olefins and triphenylphospine has been examined. Addition of 2 to solutions of alkenes causes downfield shifts (0.1–0.6 ppm) of their olefinic proton n.m.r. absorptions indicative of πcomplexation. Isolable adducts were obtained and characterized for the ligands cyclooctadiene, norbornadiene, norbornylene, cycloheptatriene, 3-methylcyclohexene, and triphenylphosphine. Attempts to utilize 2 as an enantioselective gas chromatographic complexing agent for racemic alkenes failed, apparently due to its solution and thermal instability.
