-n-BuLi was reacted with t-butyl-1-naphthyl sulfone (I) in refluxing ether followed by either carbonization of hydrolysis to give 2-n-butyl naphthoic acid and trans-1,2-dihydro-1-t-butylsulfonyl-2-n-butylnaphthalene respectively. The most likely mechanism involves first 1,2 addition of BuLi to sulfone (I) and, in subsequent step, t-butylsulfinic acid elimination. MeLi metalates sulfone (I) at C-2 of
-n-BuLi与叔丁基-1-萘砜(I)在回流的乙醚中反应,然后进行水解碳化,得到2-正丁基萘甲酸和反式1,2-二氢-1-叔丁基磺酰基-2-正丁基萘。最可能的机理涉及首先将1,2,3 BuLi加到砜(I)中,然后在随后的步骤中消除叔丁基亚磺酸。MeLi在环的C-2处使砜(I)金属化。
