由对苯二酚合成2,5-二甲氧基对苯二苄氯锍盐

Synthesis of 2,5 Dimethoxybenzene p Dichloromethyl Sulphonium Salt from Hydroquinone

以对苯二酚为基本原料，通过改进的甲氧基化、氯甲基化、锍化３个反应合成，得到（２，５－二甲氧基对苯乙炔）单体双锍盐２，５－二甲氧基对苯二苄氯锍盐，且产率达８４％，并对每步反应的合成条件及原因进行了解释。

Dimethoxybenzene p dichloromethyl sulphonium salt as the monomer of poly(2,5 dimethoxy p phenylene vinylene) was obtained with a yield over 75% through improved methoxylation, chloromethylation and sulphonization procedures from hydroquinone. The reaction conditions were studied in detail and the synthesized products in each step were confirmed by GC/MS and 1H NMR.
