Regeneration of carbonyl compounds from the corresponding oximes

There is a continued interest in the development of procedures for the effe ctive regeneration of carbonyl compounds from the corresponding oximes, esp ecially under mild conditions. Oximes are extensively used as preferred der ivatives for purification and characterization of carbonyl compounds and th ey play an important role as protecting and selectively a-activating groups in synthetic organic chemistry. Furthermore, their synthesis from noncarbo nyl compounds provides a valid alternative pathway to carbonyl compounds. [GRAPHICS]
