The Thermal And Photolytic Rearrangements Of Isatoic Acid Diazide, Ana Alejandre Ciereszko
The Thermal And Photolytic Rearrangements Of Isatoic Acid Diazide, Ana Alejandre Ciereszko
Chemistry & Biochemistry Theses & Dissertations
The primary objective of this research has been the thermolysis and photolysis of isatoic acid diazide 1. Thermolysis in low boiling solvents produced the acylazido benzimidazolone 10, while refluxing in high boiling solvents gave rise to the imidazoindazoline 31, presumably via Curtius rearrangements.
Photolysis of the diazide in methylene chloride gave rise to two photo products, 10 and 31, while photolysis in tetrahydrofuran produced only 31.
A study of the spectral and chemical characteristics of these products have been carried out.
The Synthesis And Characterization Of The 2,2'-Bisacylazide Of 2,2'-Diphenyldicarboxylic Acid, Subrata Chatterjee
The Synthesis And Characterization Of The 2,2'-Bisacylazide Of 2,2'-Diphenyldicarboxylic Acid, Subrata Chatterjee
Chemistry & Biochemistry Theses & Dissertations
The primary objective of this investigation w2s the photolytic and thermal characterization of a newly synthesized aromatic diacylazide, the 2,2'-bisacylazide~ of 2,2'-diphenyldicarboxylic acid 19. Photolysis of the azide in acetone ~ave rise to a mixture of photoproducts, one of which is a known system, 6(5-H)-phenanthridionone 28, while photolysis of 19 in ethanol gave ris,2 to the corresponding hydroxamic acid ester 40.
