Areas of expertise: Physical Organic Chemistry, The Free radical Chemistry, The
Organic Reaction Mechanism, The Developing Strategy of Environmental Science
Technology Industrial Park.
The Directions of Research:
1. The Investigation of Free Radical Intermolecular Addition Following Free Radical
SH2' Cyclization Reactions
2. Phohotorearrangement of Propargyl Bromide as probe to Study Propargylic and
Allenic Radicals by Infrared Matrix Isolation Technique.
The Background of Research:
The free radical SH2' reaction is a concerted reaction, Using this characteristic of SH2'
reaction to apply in the free radical addition/cyclization reaction to get high
stereoselectivity and chemoselectivity of the cyclized products.
