Trifluoromethyl ether and difluoro(methylthio)methyl ether of phenols and aliphatic alcohols were selectively synthesized from the corresponding dithiocarbonates. When IF5-pyridine-HF was used alone in the reaction of the dithiocarbonate, the difluoro(methylthio)methyl ether was selectively formed. On the other hand, by the additional use of Et3N-6HF with IF5-pyridine-HF, trifluoromethyl ether was
由相应的二硫代碳酸酯选择性地合成了酚和脂族醇的三氟甲基醚和二氟(甲硫基)甲基醚。当在二硫代碳酸酯的反应中单独使用IF 5-吡啶-HF时,选择性地形成了二氟(甲硫基)甲基醚。另一方面,通过将Et 3 N-6HF与IF 5-吡啶-HF一起使用,选择性地形成了三氟甲基醚。各种官能团如酯,醚,酰胺和丙酮化物可以耐受反应条件,并且合成了各种官能化的二氟(甲硫基)甲基醚和三氟甲基醚。
