In a consecutive three-component cyclocarbopalladation, Sonogashira coupling, Michael addition sequence 4-aminopropenylidene indolones, i.e., terminally fixed push-pull chromophores, are obtained in yields as high as 99%. Most remarkable, however, is

Based upon a twofold bromine―lithium exchange with 2,5-dibromo thiophene and sequential trapping of the dilithio intermediate, organo zinc halides were generated in situ and subsequently transformed by Negishi cross-coupling to unsymmetrically subs

A novel consecutive three-component coupling-enamine addition synthesis gives access to three types of diene merocyanines in a selective fashion and in good yields. Moreover, all these push-pull systems are intensely red or yellow emissive in the sol
