Versuchsvorschrift

A mixture of 2-vinylbenzaldehyde (2.9 g, 22 mmol) and trimethylsilyl chloride (11 ml) in ethylene glycol (95 ml) was stirred for 16 h, diluted with saturated sodium bicarbonate solution, extracted with ether, dried over sodium sulphate and evaporated to afford a colourless oil (2.7 g), MS (+EI) 176 (M+), 1H NMR (CDCl3) 7.57 (1H, m), 7.53 (1H, dd, J1.5, 7.5 Hz), 7.36-7.30 (2H, m), 7.14 (1H, dd, J11, 17.4 Hz), 6.04 (1H, s) 5.69 (1H, dd, J1.3, 17.4 Hz), 5.34 (1H, dd, J1.3, 11.0 Hz), 4.18-4.04 (2H, m), 3.77-3.65 (2H, m).
