Rhodium‐Catalyzed Divergent Arylation of Alkenylsulfonium Salts with Arylboroxines

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(49)

Опубликована: Окт. 13, 2022

A ligand-controlled rhodium-catalyzed regiodivergent arylation of alkenylthianthrenium salts with arylboroxines which allows the synthesis terminal and internal alkene products in a switchable manner is reported. The use diene ligand guides reaction toward cine-arylation affording alkenes, while phosphine switches to ipso-arylation exclusively giving alkenes. Deuterium labelling studies DFT computations were carried out investigate mechanism.

Synthesis of 1,2-Diamines from Vinyl Sulfonium Salts and Arylamines

Organic Letters, Год журнала: 2022, Номер 24(35), С. 6455 - 6459

Опубликована: Авг. 29, 2022

A procedure for the synthesis of 1,2-diamines from vinyl sulfonium salts and arylamines under mild conditions was developed. This present synthetic protocol not only obviates need a transition-metal catalyst an oxidizing reagent but also features broad substrates scope. The practicability this is demonstrated by one-pot synthesis, scale-up reaction, transformations products to diverse N-heterocyclic compounds. Mechanistic studies indicate that formation aziridine plays key role during diamination process.

Palladacycle-Catalyzed Olefinic C–P Cross-Coupling of Alkenylsulfonium Salts with Diarylphosphines to Access Alkenylphosphines

Organometallics, Год журнала: 2022, Номер 41(16), С. 2342 - 2348

Опубликована: Авг. 4, 2022

An efficient olefinic C–P cross-coupling of alkenylsulfonium salts with secondary diarylphosphines is reported. The use a palladacycle enables the facile formation bond at alkenyl moiety tolerating wide range functional groups under mild conditions. This protocol provides an easy access to various alkenylphosphine products in good high yields levels stereoselectivity (E selectivity).

Highly Regioselective Dichalcogenation of Alkenyl Sulfonium Salts to Access 1,1-Dichalcogenalkenes

Organic Letters, Год журнала: 2023, Номер 25(28), С. 5324 - 5328

Опубликована: Июль 7, 2023

An unprecedented geminal olefinic dichalcogenation of alkenyl sulfonium salts with dichalcogenides ArYYAr (Y = S, Se, Te) is reported, providing various trisubstituted 1,1-dichalcogenalkenes [Ar1CH C(YAr2)2] in a highly selective manner under mild and catalyst-free conditions. The key process involves the formation two C-Y bonds via sequential cross-coupling C-H chalcogenation. A mechanistic rationale further supported by control experiments density functional theory calculations.
