A novel, three-component CN bond forming reaction is described. Reaction of diazocompounds with both azodicarboxylates and arylamines in the presence of dirhodium acetate catalyst gives good yields of the corresponding aminal with high selectivity and, in most cases, NH insertion side products were suppressed. This is the first example of a CN bond formation from the addition of ammonium ylides to

present the reaction of anilines with both diazoacetates and azodicarboxylates in the presence of catalytic amounts of triarylaminium salt giving the corresponding complex unsymmetrical aminals in high yields. This is the first example of stable radicalcationsalt promoted proton-transfer-delay three-component reaction.
