Scalar 13C 19 F spin-spin couplings between carbonyl carbons and aromatic fluorines in tricarbonylchromium complexes of biphenyl derivatives

Abstract

The 13C NMR spectra of the carbonyl carbons region of 2,2′-difluoro-6,6′-dimethylbiphenyl and 4,5-difluoro-9,10-dihydrophenanthrene tricarbonylchromium complexes are reported. The 13C- 19F couplings between carbonyl carbons and aromatic fluorines were used to determine the structures of the investigated complexes.
