摘要：

主要介绍有关配合物[Ni(Me3en)(acac)]BPh4的合成过程优化的基本思路及初步实施的结果。在引导学生认识配合物[Ni(Me3en)(acac)]BPh4的合成原理、条件和过程的基础上，以原实验合成过程要吸干合成原料Ni(NO3)2∙6H2O固体表面的游离水为切入点，在探讨水对合成体系影响的实验过程中，结合实验原理以及合成过程和条件，提出了几条不完全相同的合成途径，并通过实验进行初步探究和验证，以培养学生的问题意识与解决问题的能力。并为这个实验面向不同层次、不同教学需求的学生的广泛开展奠定了基础。

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
