    • 2O (31.8 mg, 1 mol%). The Diels-Alder reaction was carried out at 20. under argon atmosphere with magnetic stirring. The concentration of water (9 ppm) in the dichloromethane solution was measured by gas chromatography to determine the rate constant and endo/exo product ratio.

    • A mixture of 1,2-dichloroethane (15 mL) and acetonitrile (5 mL) was added by HN(SO2C8F17)2 (6.0 mmol) and tin(IV) acetate (1.5 mmol, which was stirred continuously for 15h at 50°C. The reaction mixture was then cooled to room temperature and perfluorodecane (20 mL) was added. After the perfluorodecane layer was evaporated and dried at 80°C/0.01 mmHg for 8 h, tin(IV) bis(perfluorooctanesulfonyl) amide complex was therefore obtained as a hygroscopic white powder in 96% yield (5.87 g, Anal. calcd for Sn[N(SO2C8 F17)2]4: C, 19.03; Sn, 2.94.
