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.

标 题:Catalytic boronate ester synthesis from boron reagents and hydrocarbons
发明人：SMITH III MILTON R
权利人:UNIV MICHIGAN STATE
摘要:A process for producing a ring-substituted arene borane which comprises reacting a ring-substituted arene with an HB organic compound in the presence of a catalytically effective amount of an iridium or rhodium complex with three or more substituents, excluding hydrogen, bonded to the iridium or rhodium and a phosphorus organic ligand, which is at least in part bonded to the iridium or rhodium, to form the ring-substituted arene borane. Also provided are catalytic compounds for catalyzing the process comprising an iridium or rhodium complex with three or substituents, excluding hydrogen, bonded to the iridium or rhodium and optionally, a phosphorus organic ligand, which is at least in part bonded to the iridium or rhodium.
