Ring expansion reactions of alkoxides and their application toward synthesis of large ring hormone models

Creator:: Seitz, Earl Philip
Abstract:: The potassium salts of a series of 1-vinylcycloalk-3-en-l-ols were found to undergo ring expanding [1, 3]-sigmatropic shifts at 25° when dissolved in hexamethylphosphoramide (HMPA) or 1, 2-dimethoxyethane (DME) with 18-crown-6. The yields and reaction rates were compared with those of the corresponding Siloxy-Cope ring expansions. These anionic cases showed about...

The use of stable activable tracer in hydrology

Creator:: Chick, Stephen W. K.
Abstract:: A tracer method utilizing stable activable tracers (involving rare earth nuclides with short-lived t[subscript 1/2] < 1 day} activation products) for tracing fluid bound substances in fresh water is explored. Simulated laboratory studies showed these tracers (Dy and in) when chelated with diethylenetriamine2entaacetic acid a7i1W to be stable ( <20%)...

Two studies concerning rare earth elements : I. Rare earth DTPA complexes as estuarine hydrological tracers : II. Rare earth elemental concentrations in some Pacific Northwest rivers

Creator:: Keasler, Kenneth M.
Abstract:: Two studies were conducted involving rare earth elements. In the first study, the use of rare earth diethylenetriaminepentaacetic acid (DTPA) complexes as stable actiable tracers, a method of stable-isotope tracing with post-sampling neutron activation analysis, was explored. The persistence of rare earth DTPA complexes in estuarine waters was measured in...

High-resolution X-ray photoelectron spectroscopy of CO₂ and other small molecules

Creator:: Hahne, Jeffrey A.
Abstract:: The carbon is photoelectron spectrum of CO₂ has been measured with very high photon energy resolution. The natural lifetime of the carbon is hole state has been determined from a series of spectra taken at photon energies of 308, 320, and 330 eV. The measured values of the lifetimes show...

Electronegativity of -SF₅, -CF₃SO₂, and -SO₂F mmeasured with X-ray photoelectron spectroscopy

Creator:: True, Jan E.
Abstract:: The electronegativities of -SF₅, -CF₃SO₂, and -SO₂F have been measured with gas phase X-ray photoelectron spectroscopy. Of these three groups previously measured values were found only for -SF₅. The electronegativities of -Cl, -Br, -CF₃, and -CF₃, were concurrently measured to determine how the findings of this research compare with other...

Fluoroboranes : I. Preparation and properties of trifluoromethyldi-n-butylborane : II. A study of doboron tetrafluoride

Creator:: Self, James Maurice
Abstract:: A large-scale preparative method for potassium di-n-butylborate in triethylamine solvent has been developed. The reaction of potassium di-n-butylborate I with trifluoromethyl iodide has been shown to yield trifluoromethyl di-n-butylborane and other products. Reaction of this substance with boron trifluoride gave trifluoromethyl boron difluoride. Reactions of diboron tetrafluoride, boron tribromide, and...
