The arylation of secondary acyclic amides has been achieved with diaryliodonium salts under mild and metal-free conditions. The methodology has a wide scope, allows synthesis of tertiary amides with highly congested aryl moieties, and avoids the regioselectivity problems observed in reactions with (diacetoxyiodo)benzene.

Thermolysis of 1-(N-acetyl-N-ary)amino-2,4,6-triphenylpyridinium tetrafluoroborates a new and synthetically useful source of arylnitrenium ions under non-acidic conditions; a p-semidine-type byproduct is obtained from the phenylamino conpound.

N-Methyldiphenylamine, A, is in oxygen-free solution converted by light into N-methylcarbazole, C, and N-methyltetrahydrocarbazole, THC, via a disproportionation reaction.The precursor of C and THC is an unstable 4a,4b-dihydrocarbazole, DHC.Its decay was studied by means of flash and steady state illumination experiments at different temperatures.The primary photoproduct of the A derivative N-methyl-2,4,6-trimethyldiphenylamine, TMA, is a 4a-methyl-4b-hydrocarbazole, MDHC.Like DHC it is unstable but rearranges into stable methylhydrocarbazoles, MDHC'.It does not disproportionate like DHC.The photoproducts formed from A, deuterated A, and TMA were analyzed by means of NMR and mass spectrometry.
