Abstract
Improvements in the subject of the main patent n ° 358,737 for a process to prepare bis-stilbene compounds of the formula **(See formula)** in which A'represents an alpha-naphthyl, beta-naphthyl, pyridyl, 4-diphenylil radical or of the formula **(See formula)** (where X1 stands for hydrogen, an alkyl group containing from 1 to 4 carbon atoms -except for the p-isopropyl group-, halogen, alkoxy with 1 to 4 carbon atoms, sulfonic acid dialkylamide, sulfonic acid alkyl ester, sulfone, a carboxylic acid group or its salts, esters or amides, trifluoromethyl or a cyano group in the meta or ortho position; while X2 and X3 signify hydrogen, an alkyl group containing from 1 to 4 carbon atoms - with the exception of the group p-isopropyl-halogen or alkoxy with 1 to 4 carbon atoms, or X2 together with X3 form a methylenedioxylic group); M represents a salt-forming cation; and Y represents a hydrogen atom, halogen, an alkyl group containing 1 to 4 carbon atoms, or an alkoxy group containing 1 to 4 carbon atoms, characterized by reacting about 1 molar equivalent of a compound of the formula **(See formula)** with approximately 1 molar equivalent of a compound of the formula **(See formula)** and about the molar equivalent of a compound of the formula **(See formula)** in whose formulas Y, M and A'have the meaning already stated, while one of the symbols Z1 and Z2 means one group -CHO- and the other means one of the groupings of the formulas **(See formula)** in which R represents an alkyl, aryl, cycloalkyl or aralkyl radical with possible subsequent substitution, and isolate from the reaction mixture the final product of the formula indicated at the beginning, using its solubility in water.
