Abstract

1397807 Alpha-keto-esters SNAMPROGETTI SpA 5 act 1972 [5 Oct 1971] 46067/72 Heading C2C Alpha-keto-esters are prepared by reacting an α-halo acetylenic compound of formula R-C#C-X wherein X is F, Cl, Br or I and R is an optionally substituted aliphatic, cycloaliphatic, or aromatic radical, with O 3 in the presence of an alcohol at less than 0‹ C., and reducing the resulting intermediate compounds (hydroperoxides) to produce the desired ester. In the examples the reducing agent used is sodium thiosulphate and products prepared are the methyl esters of benzoyl formic acid, α-ketohexanoic acid and α-ketooctanoic acid
