Practical Synthesis of Aromatic Dithiocarbamates [PDF]

Synthetic Communications, 2014
Oxidation-sensitive N,N-diaryl dithiocarbamates (DTCs) are synthesized in good yields by the generation of metal amide salts from N-benzoyl precursors, followed by addition of CS2. para-Substituted diphenylamines are prepared by electrophilic aromatic substitution of diphenylbenzamide and saponification. Deacylation of electron-rich species such as bis(

A Structure–Activity Relationship Study on the Antioxidant Properties of Dithiocarbamic Flavanones

Antioxidants
The antioxidant properties of 3-dithiocarbamic flavanones have been investigated. The influence of the halogen substituents on ring A of the flavanones and the nature of the secondary amine from the dithiocarbamic moiety have been accounted.
