The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Enantioselective Addition of Boronates to Acyl Imines Catalyzed by Chiral Biphenols》. Authors are Bishop, Joshua A.; Lou, Sha; Schaus, Scott E..The article about the compound:(S)-3,3′-Dibromo-1,1′-bi-2-naphtholcas:119707-74-3,SMILESS:OC1=C(Br)C=C2C=CC=CC2=C1C3=C4C=CC=CC4=CC(Br)=C3O).Synthetic Route of C20H12Br2O2. Through the article, more information about this compound (cas:119707-74-3) is conveyed.
On the big screen: A chiral biphenol catalyst screening protocol was developed for the rapid identification of enantioselective nucleophilic boronate reactions with acyl imines. The approach successfully identified a unique catalyst for the reaction of aryl, vinyl, and alkynyl boronates. Mechanistic studies demonstrate boronate ligand exchange with the catalyst is necessary for activation towards nucleophilic addition
