YieldReaction ConditionsOperation in experiment
66% Formaldehyde generated by depolymerization of 30.00 g(1.00 mol) of paraformaldehyde (preliminarily driedover P2O5) at 170-180C was passed in a stream of nitrogen through a solution of Grignard reagent prepared from 17.00 g (0.09 mol) of compound 6b in150 mL of anhydrous diethyl ether and 2.80 g(0.12 mol) of magnesium, maintaining the temperatureat 40C. The mixture was treated with 80 g of finely crushed ice, the yellow precipitate was dissolved in 80 mL of a 2 N solution of sodium sulfate, and the solution was steam-distilled. The distillate was extracted with diethyl ether (3 × 50 mL), and the combined extracts were dried over Na2SO4 and evaporated. Yield 8.00 g (66%), purity 98% (GLC), bp 103-104C(5 mm), d420 = 1.0193, nD20 = 1.5470; MRD 46.11, calcd.45.84. IR spectrum, ν, cm-1: 3360, 1050 (OH), 3080,1658, 910 (C=CH2), 3040, 730 (1,2-C6H4). 1H NMRspectrum, δ, ppm: 2.04 (3H, CH3), 2.14 s (1H, OH),4.63 s (2H, CH2OH), 4.91 q and 5.23 q (2H, =CH2, J =1.4 Hz), 7.11-7.59 m (4H, Harom). Found, %: C 80.79;H 7.94. C10H12O. Calculated, %: C 81.04; H 8.16.
