Z)-N,N-Diallyl-3-iodoacrylamide(2d, Typical Procedure To a solution of N,N-diallyl-3-propynamide (50 mg, 0.335 mmol) in CH2Cl2 (1.7 mL) were added t-BuI (200 μL, 1.67 mmol, 3 equiv) and ZnI2 (214 mg, 0.67 mmol, 2 equiv) at r.t. After 18 h, H2O (5 mL) was added, and the reaction mixture was extracted twice with CH2Cl2. The organic layers were dried over MgSO4, filtered, and concentrated under reduce pressure.

Owing to complexation of the product to zinc salts, the olefinic protons are more deshielded in the crude reaction mixture - before aqueous treatment - than in the pure isolated product 2d (δ = 7.0 ppm and 7.4 ppm with a coupling constant equal to 9.1 Hz: 6.85 ppm and 7.10 ppm with a coupling constant equal to 8.8 Hz, respectively).
