Transition-Metal-Free C–S Bond Formation: Aqueous Synthesis of S-Aryl Dithiocarbamates by The use of Stable Arenediazonium Salts Mediated by Nano-Magnetic Supported Silica Sulfonic Acid

GRAPHICAL ABSTRACT

Abstract

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 (ArN₂^{+ −}OSO₃-SiO₂@Fe₃O₄) 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.
