反応手順
The reaction conditions of Example 1 are substantially repeated employing allyl chloride (76.5 g, 1.0 mole), dimethyl carbonate (90.0 g, 1.0 mole), tetra-n--butylphosphonium bromide (6.78 g, 0.02 mole) and p-methoxyphenol (0.5 g, 0.004 mole) polymerization inhibitors. After heating for 7 hours at 150° C. and 600 psi carbon dioxide pressure, the reactor is cooled to room temperature and vented. Distillation gives 29.0 g (25 percent yield) of allyl methyl carbonate having b.p. of 79° C.-80° C. (150 torr) and 4.8 g (3.4 percent yield) of diallyl carbonate having b.p. of 107° C.-108° C. (150 torr).
