Palladium-catalysed direct synthesis of benzo[b]thiophenes from thioenols.
The one-pot conversion of thioenols into benzo[b]thiophenes was achieved by using a simple palladium catalyst such as PdCl(2) or PdCl(2)(cod).
متن کاملPalladium-catalysed direct arylation of thiophenes tolerant to silyl groups.
The palladium catalysed 5-arylation of 2-(trimethylsilyl)thiophene with aryl bromides via C-H bond functionalisation allows the synthesis of arylated silylthiophenes in only one step.
متن کاملReactivity of bromoselenophenes in palladium-catalyzed direct arylations
The reactivity of 2-bromo- and 2,5-dibromoselenophenes in Pd-catalyzed direct heteroarylation was investigated. From 2-bromoselenophene, only the most reactive heteroarenes could be employed to prepare 2-heteroarylated selenophenes; whereas, 2,5-dibromoselenophene generally gave 2,5-di(heteroarylated) selenophenes in high yields using both thiazole and thiophene derivatives. Moreover, sequentia...
متن کاملSynthesis of indole-annulated sulfur heterocycles using copper-catalysed C-N coupling and palladium-catalysed direct arylation.
A simple and efficient method for the synthesis of biologically relevant 5H-benzo[4,5][1,3]thiazino[3,2-a]indoles and 5,7-dihydroisothiochromeno[3,4-b]indoles has been developed via intramolecular copper catalysed Ullmann-type C-N coupling and palladium catalysed direct arylation from the corresponding precursors 2-(2-bromobenzylthio)-1H-indole and 2-(2-bromobenzylthio)-1-methyl-1H-indole, resp...
متن کاملDPO and POPOP carboxylate-analog sensors by sequential palladium-catalysed direct arylation of oxazole-4-carboxylates.
Sequential palladium-catalysed direct (het)arylation of oxazole-4-carboxylates is achieved to give rapid access to DPO and POPOP (di)carboxylate-analogs. Three novel DPO- and POPOP-type sensors with unusual Stokes shifts and high quantum yields are discovered.
