Process for the preparation of alpha -bromo, omega -chloroalkanes

摘要

Described is a process for easily preparing an alpha -bromo, omega -chloroalkane which is high in purity represented by the formula: Br(CH2)nCl in which n stands for an integer of 4 to 12. The process comprises reacting in an organic solvent an alpha , omega -dichloroalkane with an alpha omega -dibromoalkane. As the organic solvent, an aprotic nitrogen-containing or sulfur-containing organic solvent having a dielectric constant at 20 DEG C. of 20 or larger, for example, N,N-dimethylformamide, N,N-dimethylacetamide or N,N-dimethylimidazolidinone is preferred.
