Department of Chemistry and Biochemistry (Conference/Workshop/Seminar)

Toshiaki Murai, Section Editor, Chemistry Letters; Department of Chemistry, Faculty of Engineering, Gifu University, Japan, will present a seminar entitled, "Thiocarbonyls: Key Species for New Reactions and Functional Molecules".
Everyone is welcome!
For a decade, we have been involved in chemistry of thiocarbonyl compounds, particularly, of those, in which amino and alkoxy groups were introduced to the thiocarbonyl carbon atom. During these studies, we found several key reactions using thioformamides, thioformesters, and secondary thioamides. One is the sequential addition reaction of two different organometallic reagents to thioformamides. Second reaction we found in the generation of carbonions adjacent to the nitrogen atom under mild reaction conditions. The reaction of secondary thioamides with two equiv of butyllithium was complete within a minute to generate thioamide dianions. The dianions are highly nucleophilic and less basic. With these two new reactions, we have provided several nitrogen and sulfur atoms-containing heterocycles, some of which have shown unique photophysical properties applicable to OLED.
