majority of cases, standard 1,2- and 1,4-nucleophilic additions predominated; however, 4-nitrostyrylindolium salts underwent an unexpected dearomatising 1,8-addition with sulfur-centred nucleophiles. The enamine triene products thus produced display useful optical properties and provide a platform for novel sensor design, and the unusual 1,8-reaction pathway enables synthesis of novel molecular architecture
