Bilirubin determination in gallstones
(Fresenius' Journal of Analytical Chemistry, 1991)
The determination of bilirubin in gallstones is carried out by means of several methods, but most frequently by spectrophotometric determination of azobilirubin. We found that most of the methods were not applicable to ...
Mechanism of oxidation of 1-benzyl-1,4-dihydronicotinamide by the biologically active p-benzoquinone derivative, avarone, in a cationic micellar medium. An electrochemical approach
(Bioelectrochemistry and Bioenergetics, 1991)
The electrochemical reduction of avarone (Q), an antitumor sesquiterpenoid quinone, was investigated at various pH in aqueous ethanol containing a cationic surfactant, cetyltrimethylammonium bromide (CTAB) by cyclic and ...
Ligand field analysis of metal-oxygen interactions-II. Tris(oxalato)chromate(III)
(Polyhedron, 1991)
Ligand field analysis of [Cr(ox)3]3- has been performed using the angular overlap model (AOM) approach. The metal-oxygen interactions were treated as locally anisotropic. The Trees' correction and the explicit treatment ...
Ligand field analysis of metal-oxygen interactions-I. Tris(oxalato)cobaltate(III)
(Polyhedron, 1991)
Ligand field analysis of [Co(ox)3]3- has been performed using the angular overlap model (AOM) approach. The metal-oxygen interactions were treated as locally anisotropic. Experimental spectra were well reproduced by the ...
A simple method for preparation of secondary aromatic amines
(Synthesis, Stuttgart, 1991)
A simple and efficient method for the preparation of secondary N-alkylarylamines via reductive amination of ketones with primary aromatic amines using activated zinc/acetic acid is described. It requires only equimolar ...
