Facile Access to 3,5-Disubstituted 1,2,4-Thiadiazoles via T3P® Mediated Oxidative Dimerization of Thioamides

Key Points

• The aim was to develop an efficient method for synthesizing 3,5-disubstituted 1,2,4-thiadiazoles.
• Propyl phosphonic anhydride (T3P®) was used as a mediator.
• Oxidative dimerization was performed with aromatic and aliphatic thioamides.
• The reaction conditions were optimized for efficient synthesis.
• The method facilitated the synthesis of various 3,5-disubstituted 1,2,4-thiadiazoles.
• Significant efficiency in the reaction was noted.
