In some cases, the catalyzed mechanism may include additional steps.In a article, 1448-87-9, molcular formula is C8H5ClN2, introducing its new discovery.
1,3-Dipolar Character of Six-membered Aromatic Rings. Part 49. 3-Oxido-1-(4-pyridyl)pyridinium, 3-Oxido-1-(2-pyridyl)pyridinium, 3-Oxido-1-(quinoxolin-2-yl)pyridinium, 3-Oxido-1-(5,6-diphenyl-1,2,4-triazin-3-yl)pyridinium, and 3-Oxido-1-(5-phenyl-1,2,4-triazin-3-yl)pyridinium
The title betaines are prepared: the two triazinyl betaines undergo spontaneous thermal dimerisation, and all add a variety of 2?, 4?, and/or 6? dipolarophiles.The regio- and stereo-chemistry of the addition are elucidated and rationalised.The pyridyl adducts undergo quaternisation and ring opening to tropolones.
