Reaktionen von 3-Dimethylamino-2,2-dimethyl-2H-azirin mit aromatischen Carbonsäurehydraziden
CHIMIA, 1978 Reaction of 3-dimethylamino-2,2-dimethyl-2H-azirine (1) with salicylic acid hydrazide (2c) in acetonitrile at room temperature gives the amidrazone 3c as a primary product in 78% yield. Cyclization of 3c in methanol leads to the 1,2,5,6-tetrahydro-1,2,4-

Journal of Physical Organic Chemistry, Volume 39, Issue 4, April 2026.New calculations have been applied to the pyrolysis of pyrrole under shock‐tube conditions and to the radical‐radical reaction between allyl and •CN at low temperature and pressure, using the same mechanistic scheme for both. ABSTRACT The pyrolysis of pyrrole has previously been studied in shock‐tube experiments and in jet‐stirred reactors. The results
