Abstract

Abstract: Solutions of (7-phenylnorbornyl) lithium,-potassium, and-cesium have been prepared in THF and the methods of sample preparation discussed. These benzylic ions are unstable at ordinary temperatures in ethereal solvent. The lithium derivative has been shown to be pyramidal by low-temperature carbon-13 NMR spectroscopy. The inversion process has been studied by NMR line broadening and the activation parameters ...
