Organische Fluorverbindungen, III. Eine einfache Synthese von Brom‐fluor‐essigsäureäthylester

Abstract: Ausbeute. Sdp.o.05 87-90'. Gaschromatographisch und spektroskopisch identisch mit dem unter a) beschriebenen Produkt. Brom-fluor-essigsaureathylester (I), der mit Zink und Carbonylverbindungen aFluor-(3-hydroxy-carbonsaureester bildet 2 3 und eine wichtige C2-Komponente zum Aufbau isoprenoider Fluorverbindungen3) darstellt, wurde zuerst von sWARTS4) aus Tetrabromathan in 4 Schritten mit 1Zproz. Ausbeute erhalten. In einer 6-StufenReaktion, ausgehend von Trifluor-chlor-athylen, erielte HASZELDINES) eine Ausbeut… Show more
