    Description / Table of Contents: Studies on Selenium Compounds. LXIV. Preparation and Properties of Acid Derivatives of Phenylselenium(IV) Compounds (C6H5) 2SeX2 and (C6H5) 3SeX.Reactions of (C6H5) 2SeBr2 and (C6H5) 3SeCl with silver salts of acids are investigated. From (C6H5) 2SeBr3 and AgY (Y = N03, CH3CO3, CF3CO2, 1/2 SO4, CH3SO3, NCO) the compounds (C6H5) 2Se(NO3) 2 (C6H5) 2Se(CH3CO2) 2, (C6Hs) 2Se(CF3CO2) 2, (C6H5) 2SeSO4, (C6H5) 2Se(CH3SO3) 2 and (C6H5) 2Se(NCO) 2 are prepared. They are characterized by solubility, molecular weight and conductivity. Reaction of (C6H5) 3SeCl and AgX (X = NO3, CH3CO2) yields (C6H5) 3SeNO3 and (C6H5) 3SeCH3CO2.
    Notes: Es wird das Reaktionsverhalten von (CsHs) 2SeBr2 und (C6H5) 3SeCl mit Silbersalzen von Säuren untersucht. Aus (C6H5) 2SeBr3 und AgY (Y = NO3, CH3CO2, CF3CO2, 1/2 SO4, CH3SO3, NCO) werden (C6H5) 2Se(NO3) 2 (C6H5) 2Se(CH3CO2) 2, (C6Hs) 2Se(CF3CO2) 2, (C6H5) 2SeSO4, (C6H5) 2Se(CH3SO3) 2 und (C6H5) 2Se(NCO) 2 dargestellt. Die Verbindungen werden durch ihr Löslichkeitsverhalten, durch ihre hydrolytische und thermische Beständigkeit sowie durch ihre Molmasse und ihre Leitfähigkeit charakterisiert. (C6H5) 3SeCl reagiert mit AgX (X = NO3, CH3CO2) zu (C6H5) 3SeNO3 und (C6H5) 3SeCH3CO2.

    Description / Table of Contents: The Se(VI) molecules SeO2F2, FeSO2(OAlkyl), SeO2(OCH3)2 and SeO2[OSi(CH3)3]2 form 1: 1 complexes with the donor molecules α,α′-dipyridyl, pyridine, trialkylamine and dioxane. The main properties, especially the thermally induced rearrangement reactions of the ester complexes, are described.
    Notes: Die Se(VI)-Molekeln SeO2F2, FSeO2(OAlkyl), SeO2(OCH3)2 und SeO2[OSi(CH3)3]2 bilden mit den Donatoren D =α,α′-Dipyridyl, Pyridin, Trialkylamin und Dioxan. 1:1-Komplexe. Es werden die wichtigsten Eigenschaften der Komplexe, insbesondere die beim Erwärmen ablaufenden Umlagerungsreaktionen der Esterkomplexe beschrieben.
