Regioselectivity of the nucleophilic additions and substitutions of 3-(4ʹ,4ʹ-dimethyl-2ʹ-oxazolinyl)pyridine by organolithium compounds
(1978)
Procedures for preparing 3-(4',4'-dimethyl-2'-oxazolinyl)pyridine and 4-(4',4'-dimethyl-2'-oxazolinyl)pyridine were developed. The nucleophilic heteroaromatic addition reactions of 3-(4',4'~ dimethyl-2'-oxazolinyl)pyridine ...
Catalysis of [beta]-elimination of amino acids by pyridoxal and metal ions
(1978)
The kinetics and equilibrium measurements of a-amino acids have been investigated, under β-elimination conditions, in the presence of pyridoxal with and without catalytic metal ions. The nmr technique was applied to several ...
Electronic structure of peroxo and superoxo polyamine cobalt (III) complexes
(1978)
Electronic spectra of two mononuclear cobalt(III) superoxides, [Co(CN)₅O₂]³⁻ and [Co(s-Me₂en)₂0₂Cl] ⁺ where s-Me₂en is N,N'-dimethylethylenediamine, have been studied. An unusually low intensity for the low energy MLCT ...
Chemical fixation of dinitrogen under mild conditions
(1978)
Chemical fixation of dinitrogen has been performed under mild conditions in homogeneous and heterogeneous systems. In heterogeneous system electron donor-acceptor complexes of iron phthalocyanine, ruthenium phthalocyanine, ...
An approach to the synthesis of mitomycin
(1978)
The use of 1,8-dihydroazocines, prepared from cycloaddition reactions of activated acetylenes with 1,2-dihydropyridines, as synthons for the preparations of mitomycin was explored. Our specific aim was to test the ability ...
Physical chemical characterization of amphiphilic vesicles and drug entrapment therein
(1978)
Liposomes and surfactant vesicles were characterized as potential drug carriers in this work. Iodide ion permeabilities, extent of drug entrapment and leakage were determined for liposomes. The chemically simpler, although ...
Fluorescence of coronene
(1978)
A search was made for dual fluorescence in deoxygenated solutions of 1,2,3,4-dibenzanthracene and 1,2,5,6-dibenzanthracene in EPA and n-heptane at 77°K. A nitrogen laser was utilized for excitation and a boxcar average ...
The synthesis and characterization of thio sugar esters of diorganylarsinous acids
(1978)
The synthesis of thiosugars containing several diorganylarsino groups is described. The compounds prepared are: dihexadecyl-, di-n-octyl-, dicyclohexyl-, dibutyl-, dipropyl-, diethyl-, methyl-npropyl- and 2-hydroxyethylm ...
The electrochemical oxidation of 10[beta]-methyl-1[beta]-trans-decalol
(1978)
The electrochemical oxidation of 10β-methyl-lβ-trans-decalol (11) has been investigated using the aqueous acetonitrile - tetraethylammonium tetrafluoroborate electrolytic system with controlled and noncontrolled potential ...
An approach to synthesis of trichodiene
(1978)
The purpose of this study was to develop a novel synthetic method to synthesize trichodiene (1). This study has utilized 2-methyl- Δ¹- cyclopentenecarboxylic acid (23) as the starting material for the preparation of dienone ...
