PROCESS FOR THE PREPARATION OF ACYL CYANIDES |
摘要 |
Novel process for the preparation of a monomeric acyl cyanide of the general formula <IMAGE> (I) in which R represents optionally substituted alkyl with up to 8 carbon atoms, optionally substituted cycloalkyl with 3 to 12 carbon atoms, optionally substituted aryl or an optionally substituted 5-membered or 6-membered heterocyclic radical, which optionally can be fused with a benzene ring, which process comprises heating the corresponding dimeric acyl cyanide of the general formula <IMAGE> (II) in which R has the meaning stated above, to a temperature of from 50 DEG to 300 DEG C. in the presence of a compound having a basic reaction and rapidly removing the monomeric acyl cyanide (I) formed from the reaction mixture. |
