摘要:
Starting from 3-acylaminobenzo[b]furan-2(3H)-ones (2) 3-arylthio substituted derivatives (3) were prepared via novel N-acylimines (5). Compounds of type 3 and 5 were found to show visible chemiluminescence upon base-induced oxidation in the presence of an oxygen source. A mechanistic interpretation for this chemiluminescence reaction is proposed.
