Organic Letters, Год журнала: 2024, Номер 26(20), С. 4329 - 4334

Опубликована: Май 14, 2024

A photoinduced deuterodetriazenation of aryltriazenes with CDCl3 under catalyst-free conditions is reported. The reactions featured simple operation, ecofriendly conditions, readily available reagents, inexpensive D sources, precise site selectivity, and a wide range substrates. Since could be synthesized from arylamine, this protocol can used as general method for easily accurately incorporating deuterium into aromatic systems by using source.

Highly Efficient Palladium‐Catalyzed Suzuki Coupling of N‐Tosyl Aryltriazenes with Diarylborons for Access to Biaryls

ChemistrySelect, Год журнала: 2024, Номер 9(21)

Опубликована: Июнь 3, 2024

Abstract A highly efficient Suzuki coupling of N‐tosyl aryltriazenes with diarylborinic acids or potassium diaryldifluoroborinates is reported under weak basic conditions in aqueous DME dioxane, respectively. The shelf‐stable and easy‐to‐stoichiometry displayed reactivities comparable to the corresponding acids. Scope limitations protocol have been investigated, showing large electronic steric effects from aryltriazenes. Utility activated provides a cost‐effective operationally practical access biaryls anilines.

Palladium-Catalyzed Suzuki–Miyaura Reactions with Triazenyl-Tethered Aryl Bromides: Exploiting the Orthogonal Coupling Sites under Different Conditions

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(18), С. 13296 - 13307

Опубликована: Сен. 11, 2024

Transition-metal-catalyzed cross-coupling of arenes bearing two or more potential coupling sites is often challenging because the chemoselectivity issue. If orthogonal cross-couplings were applicable, one can develop a synthetically useful approach for consecutive functionalization starting compounds. We herein reported Suzuki-Miyaura triazenyl-substituted aryl bromides catalyzed by PdCl
