3-sulfonyloxyaryl(mesityl)iodonium triflates as 1,2-benzdiyne precursors with activation via ortho-deprotonative elimination strategy

Abstract

Preparation of functionalized analogues of 1,2-benzdiyne, from heavily substituted as well as benzofused scaffolds, is challenging. Here, the authors develop an array of 3-sulfonyloxyaryl(mesityl)iodonium triflates as 1,2-benzdiyne precursors, triggered from ortho-deprotonative elimination.
