REACTION OF HYDROXY AND CARBONYL COMPOUNDS WITH SULFUR TETRAFLUORIDE IX. REACTIONS OF GLYCOLS WITH SULFUR TETRAFLUORIDE

Selective substitution of one of the hydroxyl groups by a fluorine atom occurs in the reactions of 1,2-, 1,3-, and 1,4-glycols with sulfur tetrafluoride under mild conditions.The regioselectivity of substitution in the case of unsymmetrical glycols depends on the electronic nature of the groups present in the molecules of the initial compounds.
