Stereochemistry and mechanism of ionic cyclopropane ring cleavage by arenesulfenyl chloride addenda in quadricyclene systems
(The American Chemical Society: The Journal of Organic Chemistry, 1975-10-17)
Addition of benzenesulfenyl chloride to quadricyclenedicarboxylic acid (la) and to the corresponding dimethyl ester (1b) gave adducts [exo-5-chloro-endo-3-phenylthiotricyclo[2.2.1.0^2,6]heptane-2,exo-3-dicarboxylic acid ...
The Esterolytic activity of poly(1-methyl-4- and -5-vinylimidazole) in water
(American Chemical Society: Macromolecules, 1975-07)
The water solubility of poly(1-Me-5-VIm) has made it possible to achieve phenomenal rate enhancements and to gain even greater insight into the mechanism of catalysis by polymeric imidazoles. The poly(l-Me-5-V1m)-catalyzed ...
The Esterolytic activity of poly(N-alkylimidazoles) in ethanol-water. The poly(1-methyl-5-vinylimidazole)-catalyzed hydrolysis of p-nitrophenyl acetate and 3-nitro-4-acetoxybenzoic acid
(American Chemical Society: Macromolecules, 1975-07)
1-Methyl-4-vinylimidazole (1-Me-4-VIm) and 1-methyl-5-vinylimidazole (1-Me-5-VIm) have been synthesized and polymerized. The esterolytic activity of these polymers in 28.5% ethanol-water toward p-nitrophenyl acetate (PNPA) ...
The Esterolytic activity of poly(N-alkylimidazoles). The effect of ester chain length in the substrate and alkyl chain length in the catalyst on the esterolytic activity of poly(N-alkylimidazoles).
(American Chemical Society: Macromolecules, 1975-07)
In an effort to exploit the enhancement in catalytic activity which might be derived through hydrophobic interactions between polymeric catalyst and substrate, 1-methyl-5-vinylimidazole (l-Me-5-VIm), l-methyl-4-vinylimidazole ...
Nonlinear optimization; some applications to colorant formulations
(The Optical Society of America, 1975-06)
The total synthesis and anti-fertility activity of 6-silasteroids
(Elsevier: Tetrahedron, 1975)
4,4-Dimethyl-6-methoxy-4-sila-1-tetralone (2) was prepared by a modified literature procedure and converted to 3-methoxy-6,6-dimethyl-6-silaestra-1,3,5(10),8,14-pentaen-17β-yl acetate (5c). Catalytic hydrogenation of 5c ...
Electrochemical generation of stable arene metal tricarbonyl dianions
(The American Chemical Society, 1975)
