Deoximation of Substituted Benzophenone Oximes in Solid State: Isolation of a New Heterocyclic Derivative
Prashad, Mahavir,Bhaduri, A. P.
, p. 1074 - 1075 (2007/10/02)
A few substituted benzophenone oximes(1,2) undergo cleavage in the solid state during storage to yield the parent ketones and a labile intermediate, the structure of which has been assigned on the basis of spectral (IR, PMR) data.
