Acetanilides efficiently undergo Vilsmeier Haack cyclisation in micellar media to afford 2-chloro-3-formyl quinoline derivatives in good yields. This procedure works efficiently in CTAB (cetyl trimethyl ammonium bromide), SDS (sodium dodecyl sulphate) and TX (Triton-X-100) media under reflux conditions particularly from deactivated acetanilides in good yields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
