The crystal structures of two salts with large multi-atom ions: diphenyliodonium nitrate and isobutylammonium monoacidbis-[N, N'-bis(isobutyl)diamidodiselenophosphate]
(1972)
The structure of diphenyliodonium nitrate, (C₆H₅)₂INO₃, has been determined from X-ray single-crystal diffractometer data. The crystals are orthorhombic, space group Fdd2. The unit-cell constants are: a = 31.906(6), b = ...
The photochemistry of iminium salts : novel reactions with olefins
(1979)
The excited state chemistry of iminium salts has been explored in an attempt to uncover new organic photochemical processes. Results from these studies demonstrate that electron-rich olefins undergo efficient photoaddition ...
Analytical applications of electrode sensors
(1979)
Potentiometric titrimetry using calcium and chloride selective electrodes is investigated and a new conductimetric gas sensor is developed as an alternative to conventional potentiometric gas sensing electrodes. Complexometric ...
Atomic absorption spectroscopy of selected metals in a methyl iso-butyl ketone / water / 8-hydroxyquinoline solvent extraction system
(1971)
The methyl iso-butyl ketone / water / 8-hydroxyquinoline solvent extraction system coupled with atomic absorption spectroscopy was studied with regard to its applicability to the determination of some thirteen metals. The ...
Electroanalytical studies of arsinic and arsonic acids
(1976)
Electroanalytical studies have been made on the dialkylarsinic acids (C[subscript n]H[subscript 2n+1])₂ AsOOH (n = 2-4; c[underscore]-C₆H₁₁), the alkylarsonic acids, C[subscript n]H[subscript 2n+1]AsO₃H₂ (n = 1-8), the ...
Synthesis of bicyclic compounds by cationic [pi]-cyclization
(1978)
The basic goal of this study was the development and utilization of new methodology for synthesis of bicycle[5.4.0]undecanes, bicycle[4.4.0]decanes, bicycle[4.3.0]nonanes, and spiro[5.5]undecanes. The three aspects ...
NMR investigations of micellar systems in nonaqueous media
(1979)
The behavior of self-associating bile acid esters in nonaqueous media have been investigated using spectroscopic techniques, principally ¹H and ¹³C nuclear magnetic resonance (nmr) spectroscopy, as well as thermodynamic ...
Kinetics of the reactions of halogens with 1,1,1-trichloroethane and bond dissociation energies in selected chloroethanes
(1977)
The gas phase kinetic of the "bromine catalyzed elimination of HC1 from 1,1,1-trichloroethane was studied over the temperature range 565 to 634 K. The experimental results were found consistent with the following mechanism: ...
Characterization of ON-ON by resonance Raman and infrared spectroscopy
(1977)
The colored species (λ[subscript max] ~ 500 nm) formed form the reaction of nitric oxide with Lewis acids (BF₃, BCl₃, SiF₄, TiCl₄, and SnCl₄), SO₂, or HCL at 77°K has been characterized by resonance Raman and infrared ...
