A convenient and transition-metal-free method for the synthesis of S-aryl dithiocarbamates based on the reaction of stable arenediazonium nano-magneto silica sulfates (ArN 2 + -OSO 3 -SiO 2 @Fe 3 O 4 ) with dithiocarbamic acid at room temperature was studied. Avoiding the use of any hazardous transition metal, simple procedure, low cast and short reaction time are noteworthy advantages of this methodology.
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.
