The reaction of n-butyllithium with 1,3-benzodioxole, 1,3-benzoxathiole, and their 2,2-dimethyl derivatives has been investigated. Except with 1,3- benzoxathiole there is competition between metalation and cleavage of the ether bond. Metalation occurs ortho to the oxygen, while cleavage gives substitution, elimination and reduction products.
研究了正丁基锂与1,3-苯并二恶唑,1,3-苯并恶唑及其2,2-二甲基衍生物的反应。除1,3-苯并恶硫醇外,在金属化和醚键裂解之间存在竞争。金属化发生在氧的邻位,而裂解产生取代,消除和还原的产物。
