General reaction conditions: 2 (0.3 mmol), 1 (5 mol%), PhSiH3 (0.7 equiv.), and CH3CN (1 mL) were mixed in a tube under Ar. Isolated yields were given. The E/Z ratios were determined by 19F NMR spectroscopy. [a] Determined by 19F NMR spectroscopy. [b] Isolated yield for gram-scale synthesis: 2 l (5.0 mmol), 1 (5 mol%), PhSiH3 (0.7 equiv.), CH3CN (5 mL), 50 oC, 3 h.
