Cyclisation of radicals 6a,b is highly regioselective towards a 5-exo process; 6-endo ring closure is a minor route and their ratio depends on the substituents.No ring expansion of the five-membered radical intermediates 7a,b was observed.Radicals 27a,b give rise to 5-exo cyclisation regiospecifically.A competitive 1,5-hydrogen shift leading to imidoyl radicals was noticed.An analogous behaviour is also exhibited by vinyl radicals when allowed to add to carbon-nitrogen double bonds.

An original formation of one C-N bond and one C-C bond on the same carbenic center has been developed. This approach involves a copper-catalyzed cross-coupling reaction between 2'-bromo-biaryl-N-tosylhydrazones and different amines leading to 9H-fluoren-9-amine derivatives. This reaction proceeds under mild conditions in glycerol, an inexpensive and environmentally friendly solvent, without adding any external ligand.
Energetics of Multistep versus One-step Hydride Transfer Reactions of Reduced Nicotinamide Adenine Dinucleotide (NADH) Models with Organic Cations and p-Quinones

Free energy changes of each elementary step involved in the formal hydride transfer (HT-) reactions (including the so-called "one-step" HT- and "multistep" HT- mechanisms) of the reduced ni
