摘要：A process for producing organic substituted aromatic or heteroaromaticcompounds including biaryl and biheteroaryl compounds in a two-step reaction. In thefirst step, the aromatic or heteroaromatic compound is borylated in a reaction

comprising a borane or diborane reagent (any boron reagent where the boron reagentcontains a B—H, B—B or B—Si bond) and an iridium or rhodium catalytic complex. In thesecond step, a metal catalyst catalyzes the formation of the organic substituted aromaticor heteroaromatic compound from the borylated compound and an electrophile such asan aryl or organic halide, triflate (OSOCF), or nonaflate (OSOCF). The steps in the processcan be performed in a single reaction vessel or in separate reaction vessels. The presentinvention also provides a process for synthesis of complex polyphenylenes starting fromhalogenated aromatic compounds.
