Transition-metal-free synthesis of 3-sulfenylated chromones via KIO₃-catalyzed radical C(sp²)-H sulfenylation.

ABSTRACT: The reactions between o-hydroxylphenyl-functionalized enaminones and sulfonyl hydrazines providing 3-sulfenylated chromones via domino chromone ring construction and C(sp²)-H bond sulfenylation have been achieved under transition-metal-free conditions by using KIO₃ as the only catalyst.
