Kinetic stability of indium(III) complexes with azaporphyrins in aqueous sulfuric acid

Stability of chloro(octaphenyltetraazaporphinato)indium(III) and chloro(2,8,12,18-tetrabutyl-3,7,13,17-tetramethyl-5,15-diazaporphinato)indium(II I) in 90-98 % aqueous sulfuric acid was studied. Kinetic parameters of solvoprotolytic dissociation of the complexes were determined, and a mechanism of the reaction was proposed. Diaza substitution results in more stable complexes than tetraaza substitution. The state of chloro(2,8,12,18-tetrabutyl-3,7,13,17-tetramethyl-5,15-diazaporphinato)indium(II I) in a proton-donor medium was studied to show that the acid-base interaction involves one by one two meso-nitrogen atoms. Dissociation constants of the resulting acid forms were determined.

Extraction of gallium(III) by 1-{[2-(2,4-dichlorophenyl)-4-propyl-1,3- dioxolan-2-yl]methyl}-1H-1,2,4-triazole from hydrochloric acid solutions

The extraction of gallium(III) with 1-{[2-(2,4-dichlorophenyl)-4-propyl-1, 3-dioxolan-2- yl]methyl}-1H-1,2,4-triazole from hydrochloric acid solutions into toluene was studied. It was found that gallium( III) was efficiently extracted from 5-10 M solution

Reactions of octacyanomolybdate(V) and octacyanotungstate(V) with s 2 metal-ion reducing centers

The s2 centers, Sn(II), Ge(II), and In(I) reduce Mo v(CN)83- and Wv(CN)8 3- quantitatively to the corresponding octacyanomolybdate(IV) and -tungstate(IV) anions. Reductions by In(I) proceed 103-10 5 times as rapidly as those by Sn(II) and Ge(II). All reactions are triggered by a single electron oxidation, yielding a much more reactive s I intermediate. Reductions by Sn(II) in chloride medium proceed predominantly through the SnCl3- anion. The Ge(II)-W(CN) 83- reaction is initiated by a slow unimolecular heterolysis of the Ge(II) center, yielding very nearly linear profiles when the reductant is in excess.
