Paragraph 0037;0039-0040, (2018/10/11)
Belonging to the technical field of functional materials, the invention discloses a preparation method of an allomorph variant of [1-(4'-cyanobenzyl)pyridine][bis(maleonitriledithiolato)nickel (III)].The method utilizes I2 to oxidize [1-(4'-cyanobenzyl)pyridine]2[bis(maleonitriledithiolato)nickel (II)] to obtain [1-(4'-cyanobenzyl)pyridine][bis(maleonitriledithiolato)nickel (III)], then performing filtering at the end of the oxidation reaction, washing the filter cake N times, then dissolving the washed filter cake in acetonitrile, performing filtering, and volatilizing the filtrate for crystallization, thus obtaining the allomorph variant of bis(maleonitriledithiolato)nickel (III). The preparation method provided by the invention is simple and feasible, and the obtained product has highyield and high purity, and is suitable for industrial application.

The kinetics of the reactions of 3- and 4-substituted benzyl bromides with amines having various structures in nitrobenzene at 40 deg C were investigated.The 4-substituted benzyl bromides have higher reactivity compared with that calculated on the basis of the linear correlations according to the Hammett-Taft equation for unsubstituted and 3-substituted benzyl bromides containing electron-withdrawning substituents.The reactivity of benzyl bromides containing electron-donating substituents obeys a linear correlation with the ?+ constants.The effects of structural changes in the substrate and the nucleophile on the character of the transition states of the investigated reactions is discussed.
