Peterson (Silyl-Wittig) Methylenation of Carbonyl Compounds Using Nafion-H® Catalyzed Hydroxy-trimethylsilane Elimination of Β-hydroxysilanes
The Peterson (silyl-Wittig) methylenation of carbonyl compounds is significantly improved by convenient hydroxy-trimethylsilane elimination of the intermediate β-hydroxysilanes using perfluoroalkanesulfonic acid (Nafion-H®) catalysis. These high yield reactions proceed at room temperature, and the workup involves only filtration of the catalyst.
