Abstract

1992 pyridine derivatives with bridges pyridine derivatives with bridges R 0460 29 -184 2-Azanorbornadiene. -Treatment of 3-tosyl-2-azanorbornadiene (I) with sodium amalgam under sonication at 0 • C yields a solution containing 2azanorbornadiene (II) which cannot be isolated. (II) decomposes at 25. degree.C in THF-d8 with a half-life of about 30 minutes to give cyclopentadiene (III) and hydrogen cyanide (IV). -(MAGGINI, M.; PRATO, M.; SCORRANO, G.; Tetrahedron Lett. 32 (1991) 47, 6957-6960; Centro CNR Meccan.
