Versuchsvorschrift

c:- (A) 3-Allyloxybenzyl chloride was obtained as follows: A mixture of 3-hydroxybenzaldehyde (6 g), allyl bromide (6.25 g), and potassium carbonate (8.82 g) in DENT (30 ml) was stirred for 18 hours, poured into water (100 ml) and extracted with diethyl ether (3×150 ml). The combined organic extracts were washed with water (2×150 ml) and brine (2×150 ml), dried (magnesium sulphate) filtered and evaporated to give 2-allyloxybenzaldehyde (7.2 g).
