Procedimiento

1-Chlorooctane (37.17 g, 0.25 mole), dimethyl carbonate (90.0 g, 1.0 mole), tetra-n-butylphosphonium bromide (3.39 g, 0.01 mole) and N,N-dimethylformamide (200 ml) are heated to 115° C. for 24 hours. After work-up as described for Example 34, distillation gives 34.8 g (74 percent yield based on 1-chlorooctane) of methyl 1-octyl carbonate, b.p. 113° C.-114° C. (17 torr) and 1.9 g (5 percent yield based on n-octyl chloride) of di-1-octyl carbonate, b.p. 129° C.-130° C. (0.5 torr).
