Oxidation of 2,6-di-t-butylphenol by molecular oxygen : catalysis by cobaltous polyamine chelates
(1983)
The oxidation of 2,6-di-t-butylphenol by molecular oxygen in catalyzed by the (mu)-peroxo dicobalt(III) complexes formed by the ligands tetraethylenepentamine (tetren), 1,4,10,13-tetraaza-7-oxa-tridecane (taotd), ...
Synthetic and mechanistic investigations of organometallic reactions : oxidative cyclization of diester dienolates and mechanistic studies of dithiane reactions in the presence of hexamethylphosphoramide
(1983)
The oxidative cyclization of diester dienolates was investigated as a new synthetic method for cyclizing diesters. The proposed cyclization would use a transition metal salt to first complex with the terminal enolates to ...
Purification and characterization of Simian Virus 40 large T antigen
(1983)
Simian Virus 40 (SV40) is a small DNA virus that multiplies lytically in the rhesus monkey, and in cultured monkey cells. SV40 also causes tumors when injected into newborn hamsters, and transforms cultured hamster, rat, ...
Probing electron-transfer pathways in reductions by lithium dialkylamides
(1983)
An intriguing and unexpected reduction product was obtained from the reaction of lithium dialkylamide bases with (E)-2-tert-butyl-3-phenyloxaziridine (la) in tetrahydrofuran at 0(DEGREES). This reduction product, ...
Alkylations of isoquinoline via lithium aluminium hydride
(1983)
Lithium aluminium hydride (LAH) in tetrahydrofuran (THF) reacted rapidly with isoquinoline to give lithium tetrakis dihydroisoquinoline aluminate (LTDA). Proton and ('13)C NMR spectra indicated the presence of only 1,2- ...
The self-association of bile salts in isotonic saline
(1983)
The self-association of three bile salts has been studied by sedimentation equilibrium and vapor pressure osmometry. Sedimentation equilibrium experiments were performed on solutions of sodium cholate and sodium ursodeoxycholate ...
Chiral discrimination in the excited state of some pyrene derivatives
(1983)
Discriminatory interactions in the excited state of chiral molecules with circularly polarized light (CPL) or with other chiral molecules (chiral discrimination) have been studied using steady-state and nanosecond or ...
Organolanthanide complexes of heptamethylindenyl and related ligands : synthesis, reactions and catalytic properties
(1983)
Heptamethylindenyl complexes of lanthanum, neodymium and erbium containing one, two or three heptamethylindenyl ligands can be synthesized from the reaction of alkali metal heptamethylindenide salts and the appropriate ...
Vibrational spectroscopy of nitrogen oxides
(1983)
The first laser Raman spectra of both asymmetric dinitrogen trioxide (ONNO(,2)) and symmetric dinitrogen trioxide (ONONO) have been collected by stabilizing these species in nitric oxide matrices at 12 K. Laser irradiation ...
Electronic structure, electrochemical properties, and mechanism of the autoxidation reaction of cobalt dioxygen complexes containing 2,2'-bipyridine, 1,10-phenanthroline, 2,2':6',2"-terpyridine and several of the dimethyl substituted ligands
(1983)
Autoxidation of cobalt dioxygen complexes containing 2,2'-bipyridine, 1,10-phenanthroline, and 2,2':6',2''-terpyridine in aqueous solution results in the production of simple cobalt(III) chelates and hydrogen peroxide. At ...
