Choudhury, Shubhranshu Shekhar; Mahapatra, Shivam; Biswal, Himansu S. published an article in 2022. The article was titled 《Hydrogen bond mediated conversion of benzenenitriles and arylacetonitriles to amides: an “”on/in-water”” reaction strategy》, and you may find the article in Green Chemistry.COA of Formula: C7H4BrN The information in the text is summarized as follows:
Owing to the myriad of applications that amides have, hydration of nitriles has emerged as one of the most preferred atom-efficient synthesis methods. Being kinetically slow, this strategy requires some efficient catalysts. Herein, authors discovered choline hydroxide as an environmentally benign, metal-free and inexpensive catalyst for the hydration of aromatic and heteroaromatic nitriles on/in water with excellent yields. All the reactions proceeded under mild/moderate conditions, facilitated by the hydrogen bonds between the catalyst and the reactant or intermediate. D. functional theory (DFT) studies were used to propose the plausible reaction mechanism, which was further corroborated with kinetics measurements using quant. 19F NMR spectroscopy, thereby revealing the presence of H-bond mediated catalysis which brought down the activation energy barrier even lower than those in previous reports on using H2SO4 or Ru(OH)x/Al2O3 as catalysts. This work offers an “”on/in-water”” reaction strategy for the efficient hydration of nitriles and will pave the path towards novel routes for the com. synthesis of amides. In the experiment, the researchers used 2-Bromobenzonitrile(cas: 2042-37-7COA of Formula: C7H4BrN)
2-Bromobenzonitrile(cas: 2042-37-7) is a precursor to the quinazolinones, a class of drugs used to treat autoimmune diseases and coronary heart disease. In addition, 2-bromobenzonitrile can be used for the Suzuki coupling reaction.COA of Formula: C7H4BrN
