A variety of usefully functionalised biaryls may be prepared under neutral conditions by an intramolecular free radical ipso substitution reaction at an sp2 sulphonyl substituted carbon atom; the overall efficiency of the process being determined both by the nature and number of atoms linking the two aromatic rings and by appropriately positioned substituents on the aromatic aceeptor ring.
可以在中性条件下通过sp 2磺酰基取代的碳原子上的分子内自由基ipso取代反应制备各种有用的官能化联芳基;该方法的总效率取决于连接两个芳环的原子的性质和数量以及芳族乙酰对映体环上适当放置的取代基。
