Reductive Cleavage Of Cyclopentadienylmanganese Tricarbonyl, Mani S. Iyer
Reductive Cleavage Of Cyclopentadienylmanganese Tricarbonyl, Mani S. Iyer
Masters Theses
Since the isolation of ferrocene in 1951, it has been shown to behave like benzene and may be acylated, sulfonated, metalated, and arylated. Like benzene, it also resists hydrogenation.
Daniel Trifan and Louis Nicholas (1957) were the first to show that ferrocene can be smoothly degraded by lithium and ethylamine. The isolation of free cyclopentadienyl ion on hydrolysis of the reaction mixture indicates that the cleavage leads initially to cyclopentadienyl lithium salt. A similar procedure applied to cyclopentadienylmanganese tricarbonyl also resulted in the formation of cyclopentadienyl lithium salt. This, when added to ferrous chloride, gave ferrocene. This technique can be …
Reactions Of Aqueous Chlorine With Valine In Model Solutions And In Wastewater, Erika Forrer Mccormick
Reactions Of Aqueous Chlorine With Valine In Model Solutions And In Wastewater, Erika Forrer Mccormick
Chemistry & Biochemistry Theses & Dissertations
Solutions of the amino acid valine were chlorinated to seven chlorine-to-nitrogen mole (Cl/N) ratios and analyzed by high performance liquid chromatography, gas chromatography/mass spectroscopy, infrared spectroscopy, and nuclear magnetic resonance spectroscopy. The chlorination products found were N-chlorovaline, isobutyraldehyde, isobutyronitrile, and N-chloroisobutyraldimine. Their product distribution depends on the level of chlorination and pH. The main products identified at the lower CI/N mole ratios were N-chlorovaline and isobutyraldehyde, whereas at the higher CI/N mole ratios isobutyronitrile and N-chloroisobutyraldimine were identified as the main products. The concentration and the chlorination products of valine in municipal wastewater were also determined. The chlorination products of …
Micellar Catalysis Of Hydrolysis Of Substituted Hydroxamic Acids With Perfluorooctanoic Acid, Zhongyuan He
Micellar Catalysis Of Hydrolysis Of Substituted Hydroxamic Acids With Perfluorooctanoic Acid, Zhongyuan He
Masters Theses
The work demonstrated the effects of differently located and substituted phenyl groups, as well as aliphatic groups in the hydroxamic acids, on micellar catalysis with perfluorooctanoic acid as the reactive counterion surfactant in aqueous acetonitrile solution.
Kinetic rate constant-surfactant concentration profiles for the decano-, 2,5-dimethylphenylaceto-, 4-isopropylphenylaceto-, 4-phenylbutano-, and 6-phenyl-hexanohydroxamic acids were examined and analysis on the data obtained were reported.
The pseudo-phase ion exchange (PPIE) model has been satisfactorily applied to explain the observed micellar effects.
Further investigation into more appropriately substituted hydroxamic acids is suggested in order to obtain a more complete set of data and further evaluation.
A Study Of The Reactions Of P-Dipiperidino Benzene And Its Synthesis From 1,4-Dicyano-1,4-Dipiperidinocyclohexane, Ilias Konstantinos Dorziotis
A Study Of The Reactions Of P-Dipiperidino Benzene And Its Synthesis From 1,4-Dicyano-1,4-Dipiperidinocyclohexane, Ilias Konstantinos Dorziotis
Chemistry & Biochemistry Theses & Dissertations
Following a classical synthesis of PCP2 Williams attempted to prepare l,4-diphenyl-1,4-dipiperidino cyclohexane 41 . This approach involved the preparation of 1,4- dicyano-1,4-dipiperidinocyclohexane 7 and the subsequent decyanation of the compound with phenylmagnesium bromide to produce 4. This attempt failed, however, as only the monophenylated product, 8, was thought to be obtained. This product had unique reactivity, producing a blue intermediate upon treatment with halogen in both aqueous and non aqueous media. The same intermediate was produced upon irradiation of a chloroform solution of this product with sunlight or UV light in a UV chamber, with the …
