External Switched Catalysts

The ability to build complex molecules using non-stoichiometric methodologies is intrinsic to future sustainability and developments in the synthesis of pharmaceutical compounds, materials, and fine chemicals. In this context, the area of homogeneous catalysis plays a central role in rendering molecular transformations more energetically efficient and environmentally more benign. Numerous syntheses use multistep sequences (often involving different catalysts) to deliver the end-product with sequential purification and reactions. In an idealized multistep synthesis, several steps could be completed in a single flask with a single final purification. We envisage one synthetic strategy to accomplish multistep processes that would involve switching on catalytic reactions at appropriate moments using a remote stimulus (light is the most obvious option).
