Abstract

Abstract: The effects of the [2.2] paracyclophanyl nucleus on the kinetics and stereochemistry of carbonium reactions at asymmetric carbon atoms QI and/3 to the system have been examined. Hydrolysis in 9: l dioxane-water of the trichloroacetate of the a-and &diastereomers of 4-(l-hydroxyethyl)-[2.2] paracycl0phane both gave 1: 1 mixtures of the corresponding a and, B alcohols, and at rates (first order) that differed by only about 10%. ...
