Research in our group is focused on the development of green or environmental sustainable methods for amine synthesis.  Specifically, we are interested in developing new reactions using environmentally friendly metals such as Fe and renewable sources such as air and sunlight.

Two research areas are currently ongoing in the Zheng group. The first area involves the use of 2H-azirines as substrates in Fe-catalyzed transformations.  2H-Azirines are the smallest unsaturated nitrogen-containing heterocycles. Their ring strain, estimated to be about 48 kcal/mol, contributes significantly to their high reactivity.  We recently developed a general method for the synthesis of 2,3-disubstituted indoles.  The key feature of this method is amination of aromatic C-H bonds via FeCl2-catalyzed ring opening of 2H-azirines.





The second area involves harnessing the synthetic potential of nitrogen radical cations generated by visible light photocatalysis.  We recently developed a new method for cleavage of N-N bonds of hydrazines and hydrazides using using [Ru(bpyrz)3]•2H2O, visible light, and air.
