Scalar 13C, 19F spin—spin couplings between carbonyl carbons and aromatic fluorine in chelate (η 6-fluorobenzyl)-diphenylphosphitodicarbonylchromium complexes

Abstract

The 13C NMR spectra of (η 6-2-, -3-, and -4-fluorobenzyl)diphenylphosphitodicarbonylchromiums have been recorded. An attempt to rationalize the 13C, 19F couplings between carbonyl carbons and aromatic fluorine in regard to the stereochemistry was undertaken.
