The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
Durch Abänderung der üblichen Reaktionsführung werden bei der Aldehydsynthese mit a,a‐Dichlormethylether (II) ausgehend von Aromaten wie (I) bessere Ausbeuten und die Vermeidung von Nebenprodukten wie (IV) erreicht.
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.
