The first direct and selective 3, 6‐di‐thiolation and 3, 6‐di‐selenylation of carbazoles using
diaryl disulfides/diselenide as the sulfur/selenium source were demonstrated. This simple …

A sequential multistep reaction toward 5-thio-or 5-selenotriazoles has been established by
generation of both copper (I) triazolides and sulfenylating or selenylating agents in situ …

A novel S 8-mediated approach to benzothiazoles/benzoselenazoles from bis (2-
aminophenyl) disulfides/diselenides and phenylacetylenes or styrenes has been developed …

Highly efficient and practical carbon–chalcogen (S, Se) and amide bonds formation
methodologies for the synthesis of thio-and seleno-acetamides were developed, via the …

Abstract A Cu (II)-catalyzed Csp2-Se and Csp2-Sulfur bond formation was achieved with
moderate to good yields without the aid of Lewis acid and base. The reaction is compatible …

A direct C2–H thiolation of azoles with Bunte salts was achieved under the combined action
of copper and silver salts. This protocol could furnish various substituted 2-thioazoles in …

The insertion of selenium was achieved in the form of mono-selenides and di-selenides for
the preparation of novel bis-heterocyclic compounds. This method is more general and …

Sulfur: Access to Thiazole-2-thiones | Organic Letters ACS ACS Publications C&EN CAS Find …

A one-pot, Cu-catalyzed direct C–H arylselenation protocol using elemental Se and aryl
iodides was developed for nitro-substituted, N-alkylated pyrazoles, imidazoles and other …

Sodium carbonate-promoted facile synthesis of 5-amino-1, 2, 4-thiadiazoles and 5-amino-1,
2, 4-selenadiazoles with elemental sulfur and selenium, respectively, was developed. This …
