The pseudoortho (4a) and the pseudogeminal <2.2>(2,5)pyrazinophane (4b) have been synthesized via 1,6-Hofmann elimination of <(5-methyl-2-pyrazinyl)methyl>trimethylammonium hydroxide (2b) and dimerization of the generated 2,5-dihydro-2,5-bis(methylene)pyrazine (3).The molecular structures of both isomers, 4a and 4b, were determined by X-ray analysis.
