cze Jak silné elektronakceptory skutečně jsou? Studium elektronických vlastností chrom-Pentacarbonyl(dimethylamino)methylenové skupiny ve Fischerových karbenových komplexech. Byly syntetizovány čtyři benzoové kyseliny nesoucí pentakarbonyl(dimethylamino)methylenovou (G) a methylovou skupinu (3-G, 4-G, 3-Me-4-G, 4-Me-3-G). Byly měřeny jejich disociační konstanty v ethanolu a DMF. Byly popsány pozorované substituční efekty (CO)5Cr=C[N(CH3)2] skupiny.
eng How Strong Electron Acceptors they really are? Determination of Electronic Properties of Chromium Pentacarbonyl(dimethylamino)methylene Group in Fischer Carbene Complexes. Four benzoic acids bearing pentacarbonyl(dimethylamino)methylene group (G) and methyl were prepared (3-G, 4-G, 3-Me-4-G, 4-Me-3-G), and their dissociation constants were established in ethanol and DMF. Substituent effects of (CO)5Cr=C[N(CH3)2] group were described.
