1,3-Bis(dimethylamino)isoquinolines(1a–d) dimerise in the presence of silver perchlorate to yield the C-protonated diperchlorates (2a–d), which are irreversibly deprotonated to the corresponding hindered 4,4′-bi-isoquinolyls (3a–d); the dimerisation also occurs by cyclic voltammetry.

A process for producing an olefin copolymerization catalyst, comprising the step of contacting, with one another, (A) a solid catalyst component containing a titanium atom, a magnesium atom and a halogen atom, (B) an organoaluminum compound and/or organoaluminumoxy compound, and (C) a nitrogen-containing aromatic heterocyclic compound, whose one or more carbon atoms adjacent to its nitrogen atom are linked to an electron-donating group, or a group containing an electron-donating group; and a process for producing an olefin copolymer using the an olefin copolymerization catalyst.
