- Palladium/tetraphosphine catalyzed suzuki cross-coupling of heteroarylboronic acids with aryl halides
-
(Chemical Equation Presented) cis,cis,cis-1,2,3,4- Tetrakis(diphenylphosphinomethyl)cyclopentane/[PdCl(C3H 5)]2 efficiently catalyses the Suzuki reaction of heteroarylboronic acids with aryl bromides and also the coupling of arylboronic acids with heteroaryl bromides. The coupling of thiophene- or benzothiopheneboronic acids, furan- or benzofuranboronic acids and 3-pyridineboronic acid with a variety of aryl bromides gave the corresponding coupling products in good yields. However, in most cases, better results in terms of ratio substrate/catalyst were obtained for the reverse reaction using heteroaryl bromides with arylboronic acids.

- An expedient palladium-mediated route to 3-arylfurans
-
A facile route to 3-arylfurans has been developed by employing the Heck reaction between 2,5-dihydro-2,5-dimethoxyfuran and aryl iodides as the key step.
