Various 2-, 3- and 4-substituted iodobenzenes were aminocarbonylated using aminothiazole and aminothiadiazole derivatives in palladium-catalysed reaction. The reaction is chemospecific toward the corresponding carboxamides. Consequently, the application of the above N-nucleophiles provided the N-1,3-thiazol-2-yl- and N-1,3,4-thiadiazol-2-ylcarboxamides in moderate to high yields. Due to the facile

An efficient and practical methodology for the synthesis of (benzo)thiazoles-containing amides through pyridine-mediated acylation of 2‐amino(benzo)thiazoles under ultrasonic irradiation was developed. The short reaction time (within 1 min), good functional group tolerance, experimental simplicity and ease of scale-up were salient features of the present strategy, which enables straightforward access
