（H6-芳烃）Cr（CO）3络合物仅对空气具有中等敏感性，并且可以容易且廉价地从有机仓库中已经发现的大多数芳烃制备。由于教师可以让每个学生准备不同的复合物，他们是学生指导的“发现研究”实验室项目的理想目标。学生团队可以比较他们的合成和他们的产品的物理，光谱和电化学性质如何作为芳烃结构的函数而变化。由此产生的经验结构/性能的相关性，然后可以合理化的各种键合模型。讨论（H6-芳烃）铬（CO）3化学适合学生讲义包括沿着与建议，扩大这个实验，以创建多步骤的有机和无机合成项目。此外，还介绍了用相对简单的玻璃器皿进行合成的一般步骤，微型和常规规模的反应步骤实例，进行合成的实际提示，以及对合成反应的讨论。
(h6-Arene)Cr(CO)3 complexes are only moderately air sensitive and can easily and inexpensively be prepared from most of the arenes already found in organic stockrooms. Since instructors can have each student prepare a different complex, they are ideal targets for student directed "discovery research" lab projects. Teams of students can compare how their syntheses and the physical, spectroscopic, and electrochemical properties of their products vary as a function of the arenes’ structures. The resulting empirical structure/property correlations can then be rationalized in terms of various bonding models. A discussion of (h6-arene)Cr(CO)3 chemistry suitable for student handouts is included along with suggestions for extending this experiment to create multi-step organic and inorganic synthesis projects. In addition, generic procedures for the syntheses using relatively simple glassware, example reaction procedures at both micro and conventional scales, practical hints for carrying out the syntheses, a dis...
