1,3-Benzodithiole tetraoxide (BDT) 4 is more reactive in alkylation reactions than the commonly used bis(benzenesulfonyl)methane (1). This is demonstrated notably in dialkylations with sterically demanding alkyl halides. Besides its ready access and larger scope of applications, BDT has two other advantages over 1, a lower molecular weight and higher crystallinity of its alkylated derivatives. As in
1,3-苄二硫代四氧化物(BDT)4在烷基化反应中比常用的双(苯磺酰基)甲烷(1)更具反应性。这在用空间上需要的烷基卤化物进行的二烷基化中得到了明显证明。除了易于使用和更大的应用范围外,BDT还具有优于1的两个其他优点:其烷基化衍生物的分子量较低且结晶度较高。与1一样,通过用甲醇中的Mg还原,BDT中的砜基很容易裂解。
