Abstract: | 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. |
