Interactions and catalysis in normal and reversed micellar systems
(1976)
Rate constants for the mutarotation of a-D-giucose and B-D-glucose in dipolar aprotic solvent: N,N-dimethylacetamide (DMAC) in the presence of dodecylammonium propionate is greater by a factor of 2,500 for α-anomer and ...
The Diels-Alder reactions of trialkyl 3-phosphonoacrylates
(1976)
A preparative separation of the cis- and transtrimethyl 3-phosphonoacrylates was accomplished by High Speed Liquid Chromatography (HSLC), The trans-trimethyl 3-phosphonoacrylate was treated with cyclopentadiene to yield a ...
Structure and reactivity of sulfur-containing molecules adsorbed on magnesium oxide
(1976)
Sulfur dioxide was photochemically oxidized to SO₃⁻ on the surface of magnesium oxide in the presence of adsorbed water vaopor and oxygen or nitrous oxide. Water reacted with adsorbed SO₂ to increase the concentration of ...
Proton nuclear magnetic resonance and fluorescence spectroscopic investigations of normal and reversed micellar systems
(1976)
Acetophenone and benzophenone are solubilized by micellar hexadecyltrimethylammonium bromide (CTAB), hexadecylpyridinium chloride (CPyCl), sodium dodecyl sulfate (NaLS), 3-(dimethyldodecylcammonio)propane-l-sulfonate ...
The ion pair structures of arylmethyl carbanions
(1976)
The ion pair structures of various arylmethyl carbanions have been investigated with carbon-13 nuclear magnetic resonance spectroscopy. Arylmethyl carbanions exist as an equilibrium between contact and solvent separated ...
Kinetic and thermodynamic study of the interaction of vitamine B₁₂a with ligands in aqueous and micellar environments
(1976)
Rate constants for the formation, k₁(superscript app) and decomposition, k₋ ₁(superscript app), of glycine, imidazole, sodium azide, cysteine, N-butanoyl-D,L-cysteine, N-octanoyl-D,L-cysteine, and N-decanoyl-D,L-cysteine ...
Ammonia oxidation and nitric oxide reduction over Cu(II)Nay zeolites
(1976)
The catalytic activity of Cu(II)NaY zeolites in the oxidation of ammonia by molecular oxygen and by nitric oxide has been investigated for a series of copper-exchanged Y zeolites. Kinetic data were determined for the ...
Bond dissociation energies of selected fluorocarbons
(1976)
The gas phase reaction of 1,1-difluoroethylene with bromine was studied over the temperature range 550 to 620°K. The experimental data, derived from the early stages of reaction, were found to be consistent with the following ...
A mechanistic study of heteroatom di-pi-methane systems containing silicon and nitrogen
(1976)
A series of substituted divinylsilanes: dimethyl-distyryl-(11). Triphenyl-stryrl-(12), diphenyl-distyryl(13), have been prepared for photochemical study. The results of low conversion photolyses of the di-methyl-di-styrylsilane ...
Photochemical studies of a-chymotrypsin and bovine serum albumin containing triplet photosensitizers
(1976)
A new and unusual photochemical method for achieving asymmetric synthesis which uses modified proteins as triplet photosensitizers and prochiral photolabile molecules as substrates is proposed. The modified protein, phenacyl ...
