3-Acyl-1,3-diaryltriazenes as neutral and selective acylating agents
New 3-acyl-1,3-diaryltriazenes have been prepared and their reactions with amino compounds have been studied. Reactions proceed rapidly under mild conditions to give the corresponding N-acyl products. Reagents enable chemoselective acylation of aliphatic primary and secondary amines in the presence of other acylable functional groups.
