Abstract
The oxidative decarboxylation of monoamides of oxalic acid provides carbamoyl radicals, which are useful for the selective arbamoylation of protonated heteroaromatic bases; this reaction represents the first general and selective method for the N-alkyl or N-arylcarbamoylation of heteroaromatic bases. Compared to alkoxycarbonylation, this reaction is much more effective and selective, owing to more favourable polar and enthalpic effects. The importance of the steric effects is also emphasized.| File | Dimensione del file | Formato | |
