Catalytic C–C coupling through C–H arylation of arenes or heteroarenes

Mechanistic Studies of Pd‐Catalyzed Regioselective Aryl CH Bond Functionalization with Strained Alkenes: Origin of Regioselectivity

“…[1] This method simplifies the preparation of substrates and minimizes waste production due to the avoidance of pre-functionalization of one or both of the coupling partners. In particular, the functionalization of a C À H bond ortho to an aryl halide is of fundamental importance in synthetic organic chemistry and has provided new synthetic variations using this method.…”

Palladium-catalysed reactions of 6-halogeno-1,1′-binaphthyl derivatives. A detailed investigation of structure/reactivity and structure/selectivity relationships

“…A well-known and interesting aspect of the chemistry of aryl coupling is that it can take place at an arene position different from that of the original CePd bond. 18 Various aryl to aryl, 19 aryl to benzylic 20 and vinylic to aryl 21 palladium migrations have been described in the literature for biaryl compounds 19 or naphthalene derivatives. 20 Although according to DFT/B3LYP calculations of Dedieu, 22 various 1/n aryl-to-aryl palladium shifts (n¼3e6) are feasible, to the best of our knowledge, no such migrations involving binaphthyl derivatives have been reported before.…”

Synthesis of poly(5,6-difluoro-2,1,3-benzothiadiazole-alt-9,9-dioctyl-fluorene) via direct arylation polycondensation

“…[19][20][21][22][23][24][25][26][27] As the prior preparation of organometallic monomers and the treatment of toxic byproducts are not necessary, this method represents an economically and ecologically benign alternative to the conventional crosscoupling approaches. To date, there have been more and more studies addressing the utilization of DA for synthesizing p-conjugated polymers.…”
