FREE-RADICAL OXIDATION OF PARASUBSTITUTED PHENOLS BY HYPERVALENT TERT-BUTYLPEROXYIODANE AND TERT-BUTYL HYDROPEROXIDE - SYNTHESIS OF 4-(TERT-BUTYLPEROXY)-2,5-CYCLOHEXADIEN-1-ONES
M. Ochiai et al., FREE-RADICAL OXIDATION OF PARASUBSTITUTED PHENOLS BY HYPERVALENT TERT-BUTYLPEROXYIODANE AND TERT-BUTYL HYDROPEROXIDE - SYNTHESIS OF 4-(TERT-BUTYLPEROXY)-2,5-CYCLOHEXADIEN-1-ONES, Tetrahedron letters, 38(22), 1997, pp. 3927-3930
Oxidation of 4-alkylphenols 1 by 1(tert-butylperoxy)-1,2-benziodoxol-3
(1H) (2) in the presence of ren-butyl hydroperoxide affords selectivel
y 4-(tert-butylperoxy)-2,5-cyclohexadien-1-ones 3 in good yields. Evid
ence rot the involvement of free-radicals is reported. (C) 1997 Elsevi
