Research Abstract |
Biaryl compounds are versatile building blocks in the synthesis of natural products, pharmaceuticals, agricultural chemicals and π-conjugated organic materials. Therefore, the development of convenient cross-coupling reaction for giving biaryls is one of the important subjects in organic chemistry. I have developed the biaryl cross-coupling reaction of heteroaromatic compounds via diaryl iodonium salts, leading to various heterobiaryls. In addition, we also developed a metal-free regioselective oxidative synthesis of head-to-tail (H-T) bithiophenes using hypervalent iodine (III) reagent. This unique unsymmetrical coupling reaction was realized through the iodonium intermediate for the switching reactivity of 3-substituted thiophenes, and exclusive nucleophilicity of the neutral 3-substituted thiophenes at the 2-position.
