A greener tetraphenylporphyrin synthesis and metallation: an undergraduate teaching experiment

Summary

In this experiment, 5,10,15,20-tetraphenyl-21H,23H-porphyrin (H2TPP) is synthesized on the microscale using an optimized procedure with a research-grade microwave apparatus (CEM Discover). This experiment can also be extended to the para-substituted phenyl derivatives.

Metalloporphyrins, with an array of metals, can then be synthesized using greener routes including mechanochemical methods (with ...

Sustainable Preparation of an Earth-abundant Metal Acetylacetonate Complex

Summary

This experiment highlights the synthesis of the Earth-abundant metal complex, Fe(acac)3 (acac = acetylacetonate), using an approach that is greener than traditional published syntheses. Students will also have an opportunity to determine the magnetic susceptibility of this complex and to learn about NMR spectroscopy.
