Abstract

The synthesis of 2, 3-dihydro-4H-oxazino [2, 3-a] pyridinium bromide (IV) and its alkaline decomposition to 2-vinylpyridine and formaldehyde is described. The preparation of 2, 3- dihydroisoxazolo [2, 3-a] pyridinium bromide (VI) also is given but its alkaline decomposition yields products of unknown structure. The quaternization of 2-(P-bromoethyl)-pyridine results in dimerization and the product has structure XI rather than the simple ...
