WebIf the reaction is carried out in the presence of water, amines, or alcohols, then the corresponding amines, ureas, and carbamates are formed. It is possible to induce the Curtius rearrangement through the use of photochemical conditions—this is known as the Harger reaction.
Harger has found that the alkyl groups migrate preferentially to aryl groups, and this preference increases in the order methyl < primary < secondary < tertiary. This is probably due to steric and conformational factors, as the bulkier the R-group, the less favorable the conformation for phenyl migration.
