The 13C NMR spectrum of 10,10-diphenyl-9-phenanthrone was assigned unambiguously using 2D 13C,1H shift correlated NMR spectra, optimized either for one-bond or long-range 13C-1H couplings, and 2D RELAY NMR spectra.This information allowed the structures of number of substituted 10,10-diphenyl-9-phenanthrones to be decuded from their 13C NMR spectra.The results provide an insight into the mechanism of the reaction of 9-fluorenone with chlorodiphenylmethyllithium.KEY WORDS - 13C 2D long-range 13C,1H shift correlation 2D RELAY Substituted 9-phenanthrones
