[Figure not available: see fulltext.] N,O-Diprotonated forms (dications) of various quinolinecarbaldehydes were theoretically studied by DFT calculations. It was found that the most reactive electrophilic dications are expected to be generated from 2- and
Iron-catalyzed C-H bond functionalization for the exclusive synthesis of pyrido[1,2-a]indoles or triarylmethanols

The efficient and selective iron-catalyzed C-H activation of 2-benzhydrylpyridine derivatives was employed for the preparation of pyrido[1,2-a]indoles through an intramolecular C-H amination reaction. In the presence of molecular oxygen as the sole oxidant, the same 2-benzhydrylpyridines were also used for the synthesis of the corresponding tertiary alcohols. In these approaches, the iron catalyst was used to selectively activate the C(sp2)-H bond of 2-benzhydrylpyridine, in the case of the intramolecular ring-closing C-H amination reaction in which the pyridine nitrogen atom was a directing group as well as a nucleophile, and the C(sp3)-H bond of the same compound, in the case of the oxidation reaction to give the corresponding triaryl carbinol.

A highly efficient and selective palladium-catalyzed diarylation of (2-azaaryl)methanes at the methyl group is described. Aryl chlorides proved reactive enough. A palladium η3-azaallyl intermediate has been identified on the basis of DFT studies.

Direct arylation of aryl(azaaryl)methanes with aryl halidas takes place at the benzylic position in the presence of a hydroxide base under palladium catalysis to yield triarylmethanes
The superacid induced condensation of quinolinecarboxaldehydes with arenes

A variety of quinolinecarboxaldehydes have been reacted with arenes in the Bronsted superacid, CF3SO3H (triflic acid) to give condensation products in good to excellent yields (52-99%). The quinolinecarboxaldehydes are significantly
