1,4-Di-o-tolyl-2,3-naphthoquinone 1, produced by lead tetraacetate oxidation of 2,3-dihydroxy-1,4-di-o-tolylnaphthalene 2 at -30 deg C, is sufficiently stable to allow purification involving aqueous work-up and low temperature chromatography.It has been c

5,6-Dimethoxy-1,3-diphenylinden-2-one 4 and 5,6-dimethoxy-1,3-di-o-tolylinden-2-one 5 have been generated by dehydrobromination of 1-bromo-5,6-dimethoxy-1,3-diarylindan-2-ones.They appear more stable than the corresponding inden-2-ones lacking methoxyl substituents.In particular, 5 fails to dimerise at 20 deg C whereas other known inden-2-ones dimerise even at low temperature. 6,7-Dimethoxy-1,4-diphenyl-2,3-naphthoquinone 8 generated by lead tetraacetate oxidation of the corresponding dihydroxynaphthalene appears less persistent than the corresponding quinone lacking methoxyl substituents, perhaps because of easier reaction with lead tetraacetate.

The 2,3-naphthoquinones 1 (R = Ph, o-tolyl, COPh, Cl and Prn) can be generated by desilylation-debromination induced by fluoride ion (4; arrows) and trapped as the adducts 5 with norbornadiene.

1,4-Di-o-tolyl-2,3-naphthoquinone (1), produced by lead tetra-acetate oxidation of 1,4-di-o-tolylnaphthalene-2,3-diol (7) at -30 deg C is sufficiently stable to allow purification involving aqueous work-up and low temperature chromatography; it has been c
