Laser Flash Photolysis of Aza-substituted Aromatic Diazoalkyl ketones

Abstract

Photolysis of diazo ketone is one of the popular method to generate ketenes. We are intersted in the effect of aza-aromatic derivatives which may be effective on the formation of ketenes and their reactivities. Our studies carried out with using laser flash photolysis with the detection of UV-visible and infrared spectroscopy.Hydration and amination of ketenes which were formed by laser irradiation were influenced by the basicity of the nitrogen atom. The lone pair electrons of the nitrogen captured intramolecularly the first formed ketocarbene and ylide compounds are formed.
