1,4-Naphthoquinones, VII: C-Methylation of 1,4-Naphthoquinones

Article abstract of DOI:10.1002/ardp.19843170706

The action of Fenton's reagent on dimethyl sulfoxide results in carbon methylation of the quinoid system of 1,4-naphthoquinones by .CH3 under particularly mild conditions.The results depend on the substitution pattern at positions 2 and 3 and on the suitable protection of the OH group at position 5.
