A convenient ultrasound-assisted one-pot synthesis of N -acylcyanamides starting from readily available carboxylic acids and sodium cyanamide has been developed. Upon activation in the presence of trichloroisocyanuric acid (TCCA) and triphenylphosphine, a range of carboxylic acids was converted into N -acylcyanamides in good to excellent yields within 10 minutes at room temperature without base. Remarkably, N -acyl-substituted imidazolones were readily accessible through guanylation-cyclization of the in situ generated N -acylcyanamides.

A novel and convenient protocol for the synthesis of N-cyanobenzamides starting from readily available aryl halides and cyanamide via palladium-catalyzed aminocarbonylation has been developed. The protocol utilizes Mo(CO)6 as the CO source or CO(gas) and affords the desired N-cyanobenzamides in moderate to good yields.
