标 题 :Synthesis of yellow couplers
发明人：CRAWLEY MICHAEL W
权利人:EASTMAN KODAK CO
摘要:The invention provides a method of synthesis of a image-dye forming coupler of formula (I) wherein X is a substituent linked to the coupler by an atom of oxygen, sulfur or nitrogen R1 is an alkyl or aryl group, R2 is a hydrogen atom or an alkyl group; R3 to R7 are the same or different and selected from a hydrogen atom and substituent groups; which method comprises the reaction of a compound of formula (II) wherein R and R1 are the same or different and are as defined above for R1 and X is as defined above with a compound of formula (III) wherein R2 to R7 are as defined above, in the presence of an inert organic solvent.

标 题 :One step synthesis for quinacridone compounds
发明人：COSIMBESCU LELIA
权利人:EASTMAN KODAK CO
摘要:Disclosed is a process for forming a N,N'-diarylquinacridone compound comprising the step of reacting a N,N'-unsubstituted quinacridone compound with a haloaryl compound in the presence of a metal or metal compound to arylate the N and N' positions and form the corresponding N,N'-diarylquinacridone compound. The process is versatile and provides high yields and purity for the synthesis of N,N'-diarylquinacridone compounds.

标题 :Synthesis of pyrazolotriazole photographic dye forming color couplers and intermediates
发明人：BOSE JUDITH A; VALENTE RONALD R; AIMINO DINO; DEMEJO DEBORAH D
权利人:EASTMAN KODAK CO
摘要:Photographic pyrazolotriazole dye forming coupler compound or coupler intermediate compounds can be readily prepared by inducing an elimination-addition reaction between certain pyrazolotriazole compounds and aromatic amines in the presence of an inorganic base or formate. Yields and purity are high, and reaction time is reduced with the specific set of conditions and reactants, and environmental impact from waste is reduced. The resulting compounds can be used themselves as photographic dye forming couplers or further reacted to prepare useful coupler compounds for photographic use.

标 题 :Synthesis of unsymmetric anthracene compounds
发明人：CONLEY SCOTT R; COSIMBESCU LELIA; VREELAND WILLIAM B
权利人:EASTMAN KODAK CO
摘要:A process for forming an unsymmetric anthracene compound comprises a first step of forming a 9-perfluoroalkylsulfonate derivative of anthrone by reacting the anthrone with a perfluoroalkyl sulfonating agent, followed by a second step of contacting the reaction product with an aryl or heteroaryl boronic acid, ester or anhydride, and a palladium catalyst for a period of time sufficient to form an unsymmetric anthracene compound having at least one 9-position aromatic substituent.
