The preparation of heterocycles by [2+2+2] cyclization and inverse electron demand Dels-Alder reactions of arynes with 1,2,4-triazines
… to the preparation of tetrahydro-naphthyridines. Pyridazines could be generated if the cyclization could be accomplished with two nitriles and an alkyne, which would be a novel way to synthesize 1,2-diazines through the formation of the N-N bond. To this end, metal-catalyzed intramolecular [2 + 2 …

Synthesis and Characterization of Some Rhenium Complexes
Plastics or polymers are thought to behave oppositely from metals. Ideally, polymers behave as insulators while metals conduct electricity. Shirakawa and coworkers discovered conductive polymers in 1977.1 These conductor polymers have been extensively studied, discovering that charge transfer …
