Research Abstract

One main focus of organic chemistry is to develop a catalysis with which a complex molecule can be synthesized starting from simple substrates. In this regard, use of transition metal such as palladium, rhodium and copper has been widely studied. This is also true for the reactions using diazo carbonyl compounds as substrate. In this research project, use of environmentally benign, non-metallic Bronsted acid was chosen as a catalyst for the activation of diazocarbonyl compounds and successfully developed a couple of useful transformations.
