Jh. Clark et D. Wails, FLUORODENITRATION OF ACTIVATED DIPHENYL SULFONES USING TETRAMETHYLAMMONIUM FLUORIDE, Journal of fluorine chemistry, 70(2), 1995, pp. 201-205
Fluorodenitration of nitro-substituted diphenyl sulphones occurs readi
ly in dipolar aprotic solvents using tetramethylammonium fluoride as t
he source of fluoride, although other reactions including fluorodesulp
honylation can sometimes occur in competition.
