Reactions of arenediazonium o-benzenedisulfonimides with aliphatic triorganoindium compounds

The reaction of various arenediazonium o-benzenedisulfonimides with aliphatic triorganoindium compounds is described. Surprisingly, with triethyl- or tributylindium we obtained N-ethyl- or N-butylanilines, respectively. This is the first case in which, at least formally, the reactive site of a diazonium salt is the nitrogen atom directly bonded to the aromatic ring. In contrast, with trimethylindium we obtained only formaldehyde (aryl)hydrazones. In order to explain the difference between trimethyl- and triethylindium we have proposed some reaction mechanisms, supported by detailed density functional (DFT) calculations. The possible role of diazene/hydrazone tautomerism initially assumed was discarded and therefore three mechanisms for the key step (nucleophilic addition of the trialkylindium to the N=N double bond of diazene) were studied. For the favoured mechanism there is a difference in the energy barriers of 2 kcalmol-1 between the reactions with trimethyl- and triethylindium. This difference is explained on the basis of the different C-In bond energies in the two organometallics and it is assumed to be enough to explain their different behaviour under the experimental conditions.

Reductive N-monoalkylation of primary aromatic amines

Primary aromatic amines 1 with a variety of ring substituents are easily converted to their N-monoalkyl derivatives 3 by a simple variation of the sodium borohydride/sulfuric acid/carbonyl compound procedure previously described for their N-permethylations. The procedure is suitable for the α-minodeuterium labelling of the new N-substituent.
