Regiospecific Thermal Rearrangements of 2-Allyloxypyridine N-Oxides

Alker, David,Mageswaran, Sivapathasuntharam,Ollis, W. David,Shahriari-Zavareh, Hooshang

, p. 1631 - 1635 (2007/10/02)

The results reported of an earlier investigation of the thermal rearrangement of derivatives of 2-allyloxypyridine N-oxide have been shown to be incorrect.Only and sigmatropic rearrangements are observed and this regiospecifity supprots the view that these and rearrangements proceed by concentrated symmetry-allowed pathways.
