Efficient H-D exchange of aromatic compounds in near-critical D 2O catalysed by a polymer-supported sulphonic acid

Hydrogen atom exchange of aromatic compounds in neutral near-critical D 2O has been improved by using a polymer-supported sulphonic acid catalyst. Phenol, aniline, quinoline, and substituted aromatic hydrocarbons are selectively ring-perdeuterated in high yields with insignificant by-product formati...

Summary:Hydrogen atom exchange of aromatic compounds in neutral near-critical D 2O has been improved by using a polymer-supported sulphonic acid catalyst. Phenol, aniline, quinoline, and substituted aromatic hydrocarbons are selectively ring-perdeuterated in high yields with insignificant by-product formation at 325 dgC for 24 h in D 2O Deloxan . ® Graphic
