Carboxylic Acid to Thioamide Hydrogen Bonding
The lactam groups of dipyrrinones avidly engage in amide-amide hydrogen bonding to form dimeric association complexes in nonpolar solvents (in CHCl(3), K(D) ~25,000 M(-1) at 22°C). The corresponding thioamides (dipyrrinthiones), prepared from dipyrrinones by reaction with Lawesson’s reagent, also fo...
