An efficient and versatile generation of o-xylylenes by fluoride anion induced 1,4 elimination of o-(.alpha.-trimethylsilylalkyl)benzyltrimethylammonium halides
2-[(Trimethylsilyl)methyl]benzyl Methanesulfonates: Useful Precursors for the Generation of o-Quinodimethanes
摘要:
2-[(Trimethylsilyl)methyl]benzyl methanesulfonates react with potassium fluoride in the presence of a catalytic amount of 18-crown-6 at room temperature to give o-quinodimethanes, which are trapped with electron-deficient olefins to afford [4+2] cycloadducts in good yields.
