Abstract:

This paper mainly introduces the way of optimizating synthesis process of the [Ni(Me3en)(acac)]BPh4 complex and the preliminary results of initial effort. On the basis of guiding students to understand the synthetic principle, conditions and process of [Ni(Me3en)(acac)]BPh4 complex, we take absorbing the free water on the solid surface of Ni(NO3)2∙6H2O as the starting point, the effect of water on the synthetic system was discussed. Combined with the experimental principle, synthetic process and conditions, we propose several different synthetic approaches, and explore and verify them through the experiment. Through the above optimization processes, students' problem awareness and ability to solve problems can be cultivated, and we lay the foundation for the experiment to face students with different levels, different teaching needs and different teaching purposes.

Key words: Ni(Ⅱ) complex, Optimization design of synthesis process, Preliminary implementation results, Solvent systems, Solid-phase synthesis
