The stereochemistry of organometallic compounds. XIII: The 13C N.M.R. spectra of some tricarbonyl(arene)chromium compounds

Abstract

The 13C n.m.r, spectra of a series of tricarbonyl(arene)chromiums have been determined. The spectra are interpreted in terms of electronic effects of the substituent together with effects arising from con- formational preferences of the tricarbonylchromium residue. ��� No evidence for kinetic restriction of rotation could be found for any of the complexes at temperatures greater than -60�.
