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.

, p. 3840 - 3843 (2013/04/23)
A highly effective solvent-free protocol for the Buchwald-Hartwig amination of unactivated aryl chlorides is described. The effect of various [Pd(NHC)] pre-catalyst systems on the reactivity has been studied. [Pd(IPr*)(cin)Cl] is reported as the complex o
