An efficient and clean protocol was developed for rapid production of primary aromatic amides by aminocarbonylation with NH4HCO3. Without addition of auxiliary base, the use of solid and cheap NH4HCO3 dually as ammonia surrogate and base not only promoted aminocarbonylation over subsequent dehydration and hydrolysis of amides owing to its weak basicity, and it also made the reaction manipulation clean and simplified without the presence of stinky NH3 or organic amines. The Xantphos ligand with relatively intensive -acceptor character ((1)J(31P-77Se)=758Hz) and wide natural bite angle (beta(n)=111 degrees) was found to be indispensable for the high efficiency of this reaction.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 33208-99-0, you can contact me at any time and look forward to more communication. Recommanded Product: H-Ala-NH2.HCl.
