The different reactivity of two kinds of carbonyl groups in keto aldehyde substrates has been exploited for the synthesis of phenanthrols, naphthols, and their heteroatom-containing analogues. Key to this highly efficient and robust methodology is the catalyst-free intramolecular formal diazo carbon insertion of N-tosylhydrazones into keto C-C bonds (see scheme). Copyright

The nickel(II)acetylacetonate catalyzed reaction of 9-(α-bromobenzyl)-9-fluorenols with Grignard reagent affords 10-phenyl-9-phenanthrols in good yield under mild conditions.
