Zusammenfassung:	Disclosed are certain novel 4,4'-bis(alkoxycarbonyl)benzoin ethers which have the formula AND WHICH ARE USEFUL AS PHOTOINITIATORS OF POLYMERIZATION, E.G., IN THE FORMATION OF COATINGS AND THIN FILMS. The novel 4,4'-bis(alkoxycarbonyl)-benzoin ethers are prepared by contacting aldehydes of the formulaWITH A CYANIDE CATALYST TO FORM 4,4'-BIS(ALKOXYCARBONYL)BENZOINS OF THE FORMULA AND BY REACTING SUCH 4,4'-BIS(ALKOXYCARBONYL)BENZOINS WITH AN ALCOHOL OF THE FORMULA R1OH to form a 4,4'-bis(alkoxycarbonyl)benzoin ether of the foregoing formula. Each of R and R1 are straight or branched chain alkyl of one to 10 carbon atoms.
