Ligand-free highly effective iron/copper co-catalyzed formation of dimeric aryl ethers or sulfides

Highly selective coupling of diiodoarenes with phenols or phenthiols can be performed by using a low-cost, benign character and readily available Fe/Cu catalytic system in the absence of ligands. It is noteworthy that the desired dimeric aryl ethers or sulfides could be obtained in high yields by coupling between diiodoarenes and phenols, or diphenols with aryl iodides.

PALLADIUM-CATALYSED CYCLISATION OF 2-SUBSTITUTED HALOGENOARENES BY DEHYDROHALOGENATION

Cyclodehydrohalogenation mediated by various palladium catalysts and solvents with different bases (the most generally satisfactory system being palladium(II) acetate in NN-dimethylacetamide (DMA) with sodium carbonate as base) has been examined as a route to some heterocyclic systems.Whereas dehydrogenative cyclisation processes require stoichiometric amounts of palladium(II) reagent, the present procedure involves only catalytic amounts (0.1 molar proportion, or less), of palladium compound.The preparation of dibenzofuran, carbazole, fluorenone, 6H-dibenzothiazine-5,5-dioxide, 6H-dibenzopyran and benzofuranopyridine derivatives is described.The cyclisation of 3-benzamido-2-chloropyridine to 6-hydroxybenzonaphthiridine illustrates the regiospecificity of the process.
