1H-NMR- und IR-spektroskopische Untersuchungen zur Konformation von Hydroxymethyl-Substituenten in 2.3-Stellung an Hexachlorbicycloheptenen / 1H NMR- and IR-Spectroscopic Conformational Studies on Hydroxymethyl Substituents in the 2,3 Positions of Hexachlorobicycloheptenes

Abstract

Hexachloro-bicycloheptenes and heptadienes with hydroxymethyl-substituents in the 2 and 3 position show non-equivalence of the methylene protons in their NMR spectra. This is caused both by hindered rotation and the asymmetry of the molecules. For some molecules the spectroscopic data allow conclusions to be made concerning the conformation of the substituents.
