概要

• 論文の詳細を見る

• The vapor-phase carbonylation of alkyl chloroacetates with rhodium trichloride supported on active carbon was carried out under various conditions. The reaction equation for the preparation of dialkyl malonate from alkyl chloroacetate in the presence of alcohol with carbon monoxide is given as:<BR>CH<SUB>2</SUB>ClCOOR+ROH+CO=CH<SUB>2</SUB>(COOR)<SUB>2</SUB>+HCl<BR>The carbonylation proceeded smoothly at 175 °C with an inert solvent as well as with an alkoxide anion donor, such as alcohol, ether, and an ester. The mechanism of the rhodium trichloride-catalyzed carbonylation is probably similar to that of methanol to acetic acid.
