Application of scalar 13C 19F spin—spin couplings between carbonyl carbons and aromatic fluorine to investigation of conformation of tricarbonylchromium complexes of fluorobenzenes

Abstract

The 13C NMR spectra of several meta and para substituted (η 6-fluorobenzene)tricarbonylchromium complexes have been recorded. An attempt to apply the 13C 19F couplings between carbonyl carbons and aromatic fluorine to investigation of the Cr(CO) 3 tripod conformation was undertaken.
