Six linear nitrones,three DBN derivatives and their phosphoryl analogues,were first synthesized in this article,and the structures of their O-·2-spin trapping products,the nitroxides,were theoretically and experimentally *** theoretical calculations on the optimized geometries of the spin adducts,using DFT method at B3LYP/6-311+G(d,p)//B3LYP/6-31G(d) level,demonstrated that both the intromolecular H-bonds and their internal rotations around C—N bond are the key factors for stabilizing the spin adducts.

An NAD analogue, N-(2-thiol-ethyl)-nicotinamide (TENA), was synthesized. TENA was used to modify the Au electrode through self-assembled *** cyclic voltammetry study of the electrode was carried out. The interference of dimerization of the NAD analogues reported in the literature was successfully avoided. The results support a mechanism of an electron transfer followed by chemical reaction during part of the redox process of TENA. Some useful reaction parameters were obtained.
