标题:Process for the catalytic synthesis of biaryls and polymers from aryl compounds
发明人：SMITH III MILTON R; MALECZKA ROBERT E
权利人:UNIV MICHIGAN STATE
摘要:A process for producing organic substituted aromatic or heteroaromatic compounds including biaryl and biheteroaryl compounds in a two-step reaction. In the first step, the aromatic or heteroaromatic compound is borylated in a reaction comprising a borane or diborane reagent (any boron reagent where the boron reagent contains a B—H, B—B or B—Si bond) and an iridium or rhodium catalytic complex. In the second step, a metal catalyst catalyzes the formation of the organic substituted aromatic or heteroaromatic compound from the borylated compound and an electrophile such as an aryl or organic halide, triflate (OSO 2 CF 3 ), or nonaflate (OSO 2 C 4 F 9 ). The steps in the process can be performed in a single reaction vessel or in separate reaction vessels. The present invention also provides a process for synthesis of complex polyphenylenes starting from halogenated aromatic compounds.
