Abstract

We describe a two- or three-week experiment for junior and senior chemistry majors that involves the microscale preparation, characterization, and reactivity of a square planar macrocyclic tetraamide Cu(III) complex relevant to green chemistry. The characterization process includes significant use of ¹H NMR spectroscopy, along with the optional use of FT–IR and UV–vis spectroscopies. These labs and accompanying lab lectures and discussions create a problem-based learning environment that involves Brønsted acid–base chemistry, steric arguments, redox processes, Le Châtelier's principle, nonaqueous chemistry, solubility product constants, periodic trends, organic reactivity, and spectroscopy.
