An acylated 1,3-dicarbonyl compound is produced by rearrangement of the corresponding enol ester in the presence of a cyanide source. In one embodiment the cyanide source is employed with a molar excess of a moderate base, with respect to the enol ester. In another embodiment, the cyanide source is a stoichiometric amount, with respect to the enol ester, of potassium or lithium cyanide and a catalytic amount of a crown ether is used.

1-Acyl-2-cyanoaziridines of the formula ##STR1## wherein R is an acyl radical of a carboxylic, sulphonic, sulphinic, sulphenic, phosphonic or phosphoric acid, exhibit immune-stimulating and cancerostatic activities.
Substituted benzophenones of the formula ##STR1## in which Ph represents unsubstituted or substituted phenyl and R represents free, esterified or amidated carboxy, have anti-inflammatory and/or analgesic properties and can be used as active ingredients in medicaments. They are manufactured, for example, as follows: a compound or a mixture of compounds of the formula ##STR2## in which X.sub.1 and X.sub.2 together represent a group of the formula --C(.dbd.O)--O that is bonded via the carbonyl group to the radical Ph and X.sub.3 represents hydrogen, or one of the radicals X.sub.1 and X.sub.3 represents a group of the formula --C(.dbd.O)--Z, the other represents hydrogen and X.sub.2 represents a group R'O-- in which R' represents hydrogen or a hydroxy-protecting group, is subjected to acid treatment and the primary product is decomposed solvolytically.
