Untersuchungen Über Komplexverbindungen der β‐Ketosäureamid‐Reihe

Abstract: c) Ceratose-oktaazobenzolcarbonsaureester: lOmg Ceratose und 90 mg Arobenzolcarbonsiiurechlorid 13) werden in 2 ccm wasserfreiem Pyridin geltist und I Tag bei -15". 2 weitere Tage bei Zimmertemperatur stehengelassen. Der ausgefallene Ester wird abgesaugt und in Chloroform aufgenommen. Die Lasung chromatographiert man an Aluminiumoxyd und isoliert die Zone, die den fleischfarbenen Ester enthalt. Durch Aufkochen mit Dioxan wird der Ester vom Adsorbens gelost und durch Abklihlen auf -15" zur Kristallisation gebra… Show more

“…As early as 1957, Wolf and Wetzel carefully studied the coordination stability between copper and various substituted acetoacetanilides. They proposed the existence of trans ‐ and cis ‐isomers of these complexes 692 and found that they can be obtained by the ligand exchange of Cu(eaa) 2 ( 691 ) with acetoacetanilides (Scheme 150a) [306] . Corain et al .…”
