Carbocation Catalysis for Organic Synthesis

Published Nov 01, 2018

Shengjun Ni defended his dissertation "Carbocation Catalysis for Organic Synthesis" on 26 October 2018.

What is your dissertation about?

It is about the application of carbocations as catalysts in different chemical reactions. As one special type of Lewis acids, carbocations showed high efficiency, good flexibility and superiority over other Lewis acids in many organic reactions.

Does it have any connection to KTH’s sustainability work and the global sustainable development goals?

Yes. Greener chemistry is the goals all chemists pursuit all the time for the global sustainable development. Based on this, more catalysts should be designed and used in the organic transformations. The carbocation, which is metal-free, easily available and has different reactivity by tuning the molecular structure easily, should be an ideal catalyst for many reactions.

How can your results be used in the future?

Some results such as asymmetric catalysis with carbocation will inspire other chemists about how to design the catalyst for the asymmetric catalysis. Some results provide convenient methods for chemists to synthesize corresponding compounds. Some results can be used to synthesize new molecules which possess special activity.
