THE INVENTION OF RADICAL REACTIONS. PART XIX. THE SYNTHESIS OF VERY HINDERED QUINONES

Barton, Derek H. R.,Sas, Woijciech

, p. 3419 - 3430 (2007/10/02)

On photolysis with tungsten light, the acyl derivatives of N-hydroxy-2-thiopyridone afford carbon radicals which readily add to quinones.In the case of benzoquinone radical addition is followed by 2-thiopyridyl transfer to afford adducts of type 4.Two different procedures were developed for the conversion of type 4 compounds into hindered quinones of type 7.
