Reaction Steps

2-Pentadecyl-1-naphthol (48 , 135 mmol) was dissolved in acetic acid with slight warming. Chromic oxide (55.5 g, 555 mmol) was dissolved in 50 ml water and then 50 ml acetic acid was added. This chromic oxide solution was then added dropwise with stirring to the solution of the pentadecylnaphthol maintaining the temperature between 45°-50° C. The mixture was then stirred for several hours while slowly cooling to room temperature. The pentadecylnaphthoquinone, which had crystallized from solution was filtered off, washed with acetic acid, water, and air dried. Yield: 24 g (48 percent). (Method of L. F. Fieser et al, J. Am.
