Oxidation Hooker

Oxidation of 2-hydroxy-3-alkyl-l,4-quinones with potassium permanganate with shortening of the alkyl side chain by one methylene and the position exchange between hydroxyl and alkyl groups. [Pg.196]

Olefin formation from aldehydes and phosphonates. Workup is more advantageous than the corresponding Wittig reaction because the phosphate by-product can be washed away with water. [Pg.198]

Acid-catalyzed acylation of phenols using nitriles. [Pg.200]

The Hooker oxidation was first described in 1936, a mechanism was proposed in 1948, and a recent labelling study has provided data in support of the 1948 mechanism. Thus, Hooker oxidation of the naphthoquinone 3 gave 4 in 72% yield. [Pg.10]

Deduce a mechanism for the Hooker oxidation which is consistent with the results of the labelling study. [Pg.10]
