Molecular polarisability. A conformational study of some substituted arylcyclopropanes

Abstract

The dipole moments and molar Kerr constants of the following substituted cyclopropanes have been measured in cyclohexane solution: 1,1-dichloro-2-p-chlorophenyl-2-methylcyclopropane, 1,1-dichloro-2-p-tolylcyclopropane, 1,1-dichloro-2-mesitylcyclopropane, 1,1-dichloro-2,2-diphenylcyclopropane, 1,1-dichloro-2,2-dimethyl-3-phenylcyclopropane, 1,1-dichloro-2,2,3,3-tetramethylcyclopropane, hexabromocyclopropane, 1,1-dibron phenylcyclopropane, 1,1-dibromo-2-p-tolylcyclopropane, 1,1-dibromo-2-p-bromophenylcyclopropane, and dibromo-2,2-diphenylcyclopropane. The data are analysed to deduce the preferred solution state conformation.
