Hyperactive: A benziodoxole triflate promotes iodo(III)cyclization of alkynes tethered to a variety of nucleophilic moieties, affording benziodoxole-appended (hetero)arenes such as benzofurans, benzothiophenes, isocoumarins, indoles, and polyaromatics. These unprecedented (hetero)aryl-IIII compounds are easy to purify, air- and thermally stable, and amenable to various synthetic transformations.
过度活跃:苯并恶唑三氟甲磺酸酯可促进与多种亲核基团连接的炔烃的碘(III)环化,提供苯并恶唑烷(杂)芳烃,例如苯并呋喃,苯并噻吩,异香豆素,吲哚和聚芳烃。这些前所未有的(杂)芳基-I III化合物易于纯化,对空气和热稳定,并且可以进行各种合成转化。
