Dual Copper Photoredox C–H Alkynylation with Arylacetylenes

Organic Letters, Год журнала: 2024, Номер 26(37), С. 7822 - 7827

Опубликована: Сен. 10, 2024

In the realm of organic synthesis, direct C-H alkynylation with arylacetylenes has remained a daunting challenge due to competing annulations or alkenylation. Addressing this long-standing issue, herein we demonstrate merging copper and photocatalysis achieve elusive benzamides using arylpropiolic acids. Unlike conventional copper-mediated activations, our protocol circumvents need for high temperatures stoichiometric amounts salts metal/non-metal oxidants. The versatility developed dual photoredox system is underscored by performing other diverse functionalizations such as amination, selenylation, arylation, sulfonylation, nitration under slightly modified conditions.
