Abstract

1448646 Malonic acid dialkyl esters DYNAMIT NOBEL AG 29 Nov 1974 [1 Dec 1973] 51894/74 Heading C2C Malonic acid dialkyl esters are prepared by reacting a haloacetic acid alkyl ester with carbon monoxide and with an alcohol in the presence of, as a catalyst, at least one metal carbonyl, and in the presence of a basic compound. Preferred metal carbonyls are cobalt or iron carbonyl, e.g. CO 2 (CO) 8 .
