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.

Complexes Of The 2,2'-Bisacylhydrazide Of 3,3'-Bipyridine And The Dipicolinic Acid Dihydrazide Ligand Systems, William Leo Johnson Iii

Chemistry & Biochemistry Theses & Dissertations

The copper(II) complexes of the picolinic acid bydrazide (PH), the dipicolinic acid dibydrazide (DPH), and the 2,2'-bisacylbydrazide of 3,3'-bipyridine (DAR) ligand systems have been prepared and have been characterized by infrared spectroscopy. Coordination has been proposed to occur between the terminal amine, the amide nitrogen, and the ring nitrogen in each of the respective complexes.

Evidence for the loss of the amide hydrogen upon complexation of PH, DPH, and DAH with copper(II) has been observed by the n.m.r. study of the zinc(II) complexes of the PH and DAH ligand systems. This is in support of the structures proposed above for …

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.

The Occurrence And Distribution Of Methane In The Marine Environment, Larry Philip Atkinson

OES Faculty Publications

The distribution of methane in several anoxic marine environments is described. Maximum concentrations observed were μ mole CH₄-C/liter. The distribution of methane seems to follow that of sulfide. The data indicate that methane is derived from organic compounds not containing nitrogen or phosphorus and that its formation is much slower than that of sulfide.
