This paper describes the synthesis of diaryl ethers and sulfides by utilizing microwave heating methodology. The methodology is shown to be rapid and efficient for the coupling of phenols or thiophenol with electron-deficient aryl halides through a SNAr reaction. The scope of the protocol can be expanded to six-membered heterocycles bearing a hydroxyl group as well as to the reaction of 2-pyrimidinethiol with mildly activated aryl halides, providing heteroaryl ethers and sulfides, respectively. The advantages of the present method include the wide substrate scope, the obviation of metal catalysts, ease of product isolation, and high purity of products.
