1-Bromooctane (48.28 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 7.5 g (16 percent yield based on 1-bromooctane) of methyl 1-octyl carbonate and 4.4 g (12 percent yield based on 1-bromooctane) of di-1-octyl carbonate.
