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:Synthesis of aminoarylboronic esters and substituted anilines from arenes via catalytic C-H activation/borylation/amination and uses thereof
发明人：MALECZKA JR ROBERT E; SMITH III MILTON R; HOLMES DANIEL
权利人:UNIV MICHIGAN STATE
摘要:A process is described for synthesizing aminoarylboronic esters of the general formula n n nwherein R, R 2 , and R 3 are each an alkyl, aryl, vinyl, alkoxy, carboxylic esters, amides, or halogen; Ar is any variety of phenyl, naphthyl, anthracyl, heteroaryl; and R 1 is alkyl, hydrogen, or aryl. The aminoarylboronic esters are produced via the metal-catalyzed coupling of arylboronic esters of the general formula n n nwherein R and R 1 are any non-interfering group and X is chloro, bromo, iodo, triflates, or nonaflates to amines (primary and secondary). In particular, a process is described for the synthesis of the aminoarylboronic esters via a step-wise or tandem process in which one catalytic event is a metal-catalyzed borylation and the other catalytic event is a metal-catalyzed amination.
