Dichloromethyl alkyl ethers have been synthesized from alkyl formates (C1–C4) and oxalyl chloride in the presence of catalytic amount of N-methylformanilide. N,N-Dimethylformamide is not suitable for the reaction. The method has the advantages of simple experimental procedure, which is applicable to large scale synthesis, without use of harmful reagents.

方便的二氯甲基烷基醚的制备

在催化量的N-甲基甲酰苯胺存在下，由烷基甲酸酯（C1-C4）和草酰氯合成了二氯甲基烷基醚。N，N-二甲基甲酰胺不适合该反应。该方法具有实验过程简单，适用于大规模合成，无需使用有害试剂的优点。
