Abstract. A green chemistry activity for an upper level, one semester, inorganic chemistry course yields metalloporphyrins using microwave reaction methods. A variety of metals ions (including Zn2+, Ni2+, Fe3+, Co2+, Cu2+, and Mn2+) are inserted into biologically relevant porphyrin ligand tetraphenylporphyrin (H2TPP) using only ethyl acetate and ethanol as solvents, often with minimal work up. In addition to studying green and microwave methodology, the students use 1H NMR, FTIR, and UV-Vis spectrometers to characterize their materials.
