Formula: C7H5NO4. The Name is 4-Nitrobenzoic acid. Through research, I have a further understanding and discovery of 62-23-7
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.
