标 题:Method for preparation of an intermediate dye product
发明人：DETTY MICHAEL RAY; VIRKLER PETER ROBERT
权利人:UNIV NEW YORK STATE RES FOUND
摘要:The present invention provides a novel method for the synthesis of an intermediate dye product having the following formula: n wherein n L is S, Te, or Se; n R 1 and R 2 are either the same or different aryl or alkyl compounds; n R 3 is hydrogen or a short chain alkyl group; and n Z is an anion. n The process to formulate this intermediate compound entails reacting an R 1 -acetylene compound with an R 2 -acetylene compound (compounds A) into an enol ether compound with the R 1 and/or R 2 constituents (compound D). And from compound D, it forms into an intermediate dye compound having an L-based cyclic ring with the R 1 and/or R 2 constituents (compound F). With compound F the desired dye can be made with a greater overall yield for mass production.
