反応手順

The procedure employed in Example 30 is substantially repeated employing polystyrene-bound benzyl-tri-n-butylphosphonium chloride (2 percent cross-linked with divinylbenzene) as the catalyst. Accordingly, 15 g of the polymeric catalyst, allyl chloride (76.5 g, 1.0 mole), dimethyl carbonate (90.0 g, 1.0 mole) and p-methoxyphenol (0.5 g, 0.004 mole) are combined in a reactor and heated for 6 hours at 150° C. under 600 psi carbon dioxide. The reactor is then cooled to room temperature and vented. After separating the catalyst by filtration, allyl methyl carbonate (23.8 percent yield) and diallyl carbonate (2.0 percent yield) are obtained by distillation.
