A Technique For The Isolation And Identification Of Aliphatic Amines In Water, Peter Alan Drew
A Technique For The Isolation And Identification Of Aliphatic Amines In Water, Peter Alan Drew
Chemistry & Biochemistry Theses & Dissertations
Small, aliphatic amines added to a basic, aqueous solution (16.2 L) at a concentration of 100 parts per billion were isolated by sorption on a small column of macroreticular resin. The amines were eluted with diethyl ether; the eluate concentrated, and the compounds separated and identified by gas chromatography. The efficiency of the recovery of a-nines ranged from 5 to 28%.
A protocol for derivatizing pyrrolidine and n-pentylamine in ether with fluorinated acylating agents was developed. The method was found to be adequate for the detection of approximately 13 micrograms of &-nines in concentrated ether extract.

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 3,3'-Bipyridine, Magdy Adly Guirguis El-Fayoumy
The Synthesis And Characterization Of The 2,2'-Bisacylazide Of 3,3'-Bipyridine, Magdy Adly Guirguis El-Fayoumy
Chemistry & Biochemistry Theses & Dissertations
The primary objective of this research has been the synthesis and characterization of a new heterocyclic diacylazide, the 2,2'-bisacylazide of 3,3'-bipyridine 19. This heterocyclic diacylazide has been successfully synthesized from the phenanthrolin-5,6-dione 14, and examined with regard to its.thermal and photolytic decomposition.
Thermal decomposition of this disacylazide seems to go by a double-barreled Curtius rearrangement leading to a series of pyridonaphthyridinone (20) compounds such as 22 and 29.
An initial study of the photolysis of this bisacylazide has been initiated to examine the possible formation of nitrene-type intermediates.
