Iron porphyrin-induced activation of dioxygen via : (A) iron porphyrins and diphenylhydrazine for the hydroxylation of hydrocarbons ; (B) t-Butylhydroperoxide for the direct ketonization of methylenic carbon ; (C) iron porphyrins for the autooxygenation of 3-methylindole
(1994)
The combination of benzyl mercaptan (PhCH$sb2$SH) and (Cl$sb8$TPP)Fe$rmsp{III}$OH or (Cl$sb8$TPP)Fe$rmsp{III}$Cl produces (Cl$sb8$TPP)Fe$rmsp{III}$SCH$sb2$Ph (22). This species and other iron(III) complexes ((Cl$sb8$TPP)Fe$sp{rm ...
Structure and conformation of Th(IV)-complexes of ethylenediaminetetraacetic acid and its analogs in aqueous solution
(1971)
The thorium(IV) complexes of ethylenediaminetetraacetic acid (EDTA), diethylenetriaminepentaaceticacid (DTPA), triethylenetetraminehexaacIetic acid (TTHA) and N-hydroxyethylethylenetriaacetic acid (HEDTA) have been studied ...
Catalytic and mechanistic studies of some anionic transition metal carbonyl hydrides
(1986)
As PPN⁺ (bistriphenylphosphineimminium) salts the anionic metal hydrides HFeM(CO)₉⁻ (M = Cr, Mo, W) were shown to be olefin isomerization catalysts under mild conditions (25°C, fluorescent lighting) toward the conversion ...
The synthesis of esters, thioesters and selenoesters of dialkylarsinous acids
(1970)
Organoarsenic compounds of the type R₂AsXR' (R=alkyl, R'=alkyl or aryl and X=O, S or Se) have been reported in the literature. The methods described for the synthesis of these compounds involve multistep reactions which ...
Isolation and characterization of nitrogen heterocycle-organolithium reaction intermediates
(1970)
Several intermediates from the reactions of nitrogen heterocycles with organolithium compounds were successfully isolated and were characterized by their proton magnetic resonance (pmr) spectra. Using TMED (N,N,N',N ' ...
Factors determining ion exchange selectivity : I. Aqueous K+-H+ exchange with [alpha]-zirconium phosphate. II. Gas-solid ion exchange reactions
(1980)
The heats of K^+ - H^+ exchange have been measured calorimetrically on three samples of zirconium phosphate of widely differing crystallinity. The more crystalline exchangers both exhibit exothermic reaction over the full ...
New synthetic reactions of enolates of [alpha]-amino acid derivatives
(1980)
Hydroxyalkylation and acylation reactions of lithium enolates of amino acid derivatives 11-13 were investigated. Extensive rearrangement of 11 occurred under the reaction conditions. The lithium enolate of 12 exhibited ...
Equilibrium and non-equilibrium studies on certain chemical systems I. Equilibrium thermochemical investigations on selected sugars and spiranes. II. Shear viscosity studies on [alpha]-olefins and normal alcohols
(1974)
Precision oxygen-bomb calorimetry measurements have been conducted in three areas of investigation. The areas of investigation are: 1) the construction of a predictive standard enthalpy of formation correlation procedure ...
Enthalpies of combustion of eight branched isomeric alkanes from C₉ to C₁₆
(1968)
Accurate measurements of the enthalpies of combustion have been made on the following high-purity, liquid samples; 4-methyloctane, 3,3,5-trimethylheptane, 2,2,3,3-tetramethylhexane, 2,2,5,5-tetra-methylhexane, 2-methyldecane, ...
