Über die Bildung von Kohlenwasserstoffen bei der Einwirkung von Kalium auf Essigester

Abstract: Benzoylchlorid un ter guteni Umschutteln einggtragen und das Ganze unter RiickfluPJ etwa 1StQe. gekocht. Darauf m r d e das meiste Benzoylchlorid abdestilliert und der Ruckstand in einem Kolbchen mit niedrigem, weitcm Ansatzrohr destilliert. Die uber 360° iibergehende Fraktion wurde, nachdem sie erstarrt und auf Ton gestrichen war, durch Kochen rnit alkoholischer Kalilauge verseift. Dabei trat im Gegensatz zum oben beschriebenen Isomeren keine Spur von Fluorescenz auf. Der Alkohol wurde nun abdestilliert, der … Show more

“…It reacts rapidly and exothermically with water and alcohol at room temperature to form, respectively, ethyl acetate and ethyl orthoacetate (reactions 26 and 28), and it is hydrogenated over Raney nickel to acetaldehyde diethylacetal (reaction 40) (3). In contrast to these properties the product described by Scheibler (44,45) boiled at 77-78°C. and was isolated from an aqueous reaction mixture.…”

“…At about the same time as Staudinger and Rathsam described the preparation of VII, Scheibler and Ziegner (45) reported the isolation of the parent compound, ketene diethylacetal, as a minor reaction product from certain acetoacetic ester condensations involving ethyl acetate. Later Scheibler and coworkers (44) described detailed procedures for the preparation of this and other homologous ketene acetals.…”

“…A number of years later, Scheibler and his coworkers, in a series of investigations of the action of finely divided alkali metals on the esters of the lower fatty acids, came to the conclusion that the first product of the action of potassium upon ethyl acetate in absolute ether has the structure, CH2=C(OC2H5)(OK), this representing the sodium salt of the enolic form of the ester (306,307,303).…”
