found to catalyze the direct arylation of some functionalized halothiophene derivatives allowing the synthesis in only one step of polyfunctionalized arylated thiophenes. In the presence of 2-acetyl-3-chlorothiophene, 2-acetyl-4-chlorothiophene, 2-acetyl-3-bromothiophene diethylacetal or 2-(4-bromothiophen-2-yl)-[1,3]dioxolane, and a variety of aryl bromides, the 5-arylation products were obtained

Some ethers, such as cyclopentyl methylether and di‐n‐butyl ether, which can be considered as “greener” solvents than N,N‐dimethylacetamide (DMAc) or DMF, can be advantageously employed for the palladium‐catalyzed direct arylation of heteroaromatics. In the presence of such ethers and only 0.5–1 mol % of palladium catalysts at 125–150 °C, the direct 5‐arylation of thiazoles, thiophenes, or furans
