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

Free energy changes of each elementary step involved in the formal hydridetransfer (H(-)(T)) reactions (including the so-called "one-step" H(-)(T) and "multistep" H(-)(T) mechanisms) of the reduced nicotinamide adenine dinucleotide (NADH) models with various cations and quinones (17) were investigated either by direct thermodynamic measurements or by calculations from thermochemical cycles. Based
