Students work in groups to identify relevant steps and intermediates in 3 catalytic cycles, all the while considering bonding (and electron counting) factors. Following assignment of these steps and intermediate species, the students consider several questions related to catalysis more broadly, particularly the role of each reagent, how to speed up or slow down specific steps, and the importance of regiospecificity in certain steps.
- Students will be able to apply knowledge of fundamental organometallic reaction classes to put together a catalytic cycle
- Students will be able to consider the interplay of different steps and chemical species during catalysis, including structural factors allowing certain steps to occur
- Students will be able to explain the role of accessible species not directly on the catalytic cycle and how these relate to the desired catalysis
Students worked in groups of 3-4, allowing me to circulate and help groups as they came upon problems. After allowing sufficient time for their work (maybe 15 minutes), I had groups present their answers for discussion by the class.
