Abstract

1528462 α-Substituted-α-acyl acetamides AGFA-GEVAERT 2 Dec 1975 [3 Jan 1975] 313/75 Heading C2C Compounds which are 2- equivalent yellow forming colour couplers and have the grouping are made by reacting a compound having the grouping with an acid of formula HA in an aprotic solvent in the presence of a tetraalkyl guanidine as a condensing agent. The acids of formula HA has an acid strength in terms of pKa of 7-12 and specified are phenolic compounds and heterocyclic compounds containing an acid NH group in a ring.
