Education Highlight

The chemistry of ruthenium is extremely diverse and vast.  In addition, ruthenium complexes have been studied in the development of chemotherapeutic drugs, antimicrobial agents, catalysts and sensitizers. Compared with first-row d-block transition metal complexes, ruthenium complexes are rarely used for the undergraduate practical courses in higher education due to the high costs of heavy metal and Schlenk line.  To enhance our students’ learning and hands-on experience in the topic of second-row d-block transition metal chemistry, we have adopted a sustainable approach to successfully modify the preparation method of the selected ruthenium phosphine complexes and their respective catalytic oxidation reactions in our undergraduate (CM4199A) and postgraduate (CM5100) research projects (C. H. Eng, 2018; Q. Chen, 2023) to enhance the efficiency and the financial sustainability.  One of them has been used as the inorganic experiment in the advanced undergraduate and postgraduate practical courses, CM3191 and CM5192.  In such series of sustainable micro-scale inorganic experiments of homogenous catalysis, students had learnt how to perform air- and moisture-sensitive reactions, and determine the activity of catalyst prepared with the use of internal standard and ¹H-NMR, besides the characterization of heavy metal complex and the chemistry of ruthenium and phosphine ligands.
