A method for cobalt-catalyzed, aminoquinoline- and picolinamide-directed C(sp2)H bond alkenylation by alkynes was developed. The method shows excellent functional-group tolerance and both internal and terminal alkynes are competent substrates for the coupling. The reaction employs a Co(OAc)2⋅4 H2O catalyst, Mn(OAc)2 co-catalyst, and oxygen (from air) as a terminal oxidant. [ABSTRACT FROM AUTHOR]

The article discusses the method for copper-catalyzed, deprotonative dimerization of arenes by employing oxygen as the terminal oxidant. It states that copper is one of the first transition metals shown to promote functionalization of C-H bonds. It demonstrates that acidic C-H bonds can be arylated by aryl halides under copper analysis. It notes that such a method is tolerant to functionalities such as nitro, cyano, and amino.

The article presents chemical equations for article "Copper-Catalyzed Etherification of Arene C?H Bonds" by J. Roane and colleagues, published in "Organic Letters" in 2013 issue.

A general method for copper-catalyzed arylation of sp[sup2] C-H bonds with PK[suba]'s below 35 has been developed. The method employs aryl halide as the coupling partner, lithium alkoxide or K[sub3]PO[sub4] base, and DMF, DMPU, or mixed DMF/xylenes solvent. A variety of electron-rich and electron-poor heterocycles such as azoles, caffeine, thiophenes, benzofuran, pyridine oxides, pyridazine, and pyrimidine can be arylated. Furthermore, electron-poor arenes possessing at least two electron-withdrawing groups on a benzene ring can also be arylated. Two arylcopper-phenanthroline complex intermediates were independently synthesized. [ABSTRACT FROM AUTHOR]

A method for direct, copper-catalyzed, auxiliary-assisted fluorination of β-sp2 C-H bonds of benzoic acid derivatives and γ-sp2 C-H bonds of α,α-disubstituted benzylamine derivatives, respectively is developed. [ABSTRACT FROM AUTHOR]

Direct arylation and alkylation of amine and carboxylic acid derivatives is achieved with different aryl and alkyl iodides as well as benzyl and allyl bromides in the presence of a palladium catalyst. [ABSTRACT FROM AUTHOR]
