AboutAbout the lab
Creating compounds that make use of the characteristics of elements
The Organoelement Chemistry Lab studies how to lay the foundation of "all-element organic chemistry," which makes use of the "individuality" of every element in the periodic table.
The lab synthesizes compounds in which second-period elements such as carbon are replaced by heavier main-group elements such as silicon and phosphorus, and investigates their properties.
It also works on developing new catalysts that function with abundant elements, without using transition metals.
On the lab's website, it is also introduced under the name "Sasamori Lab."
Key terms
- Heavier main-group elements
- Main-group elements in the third period and beyond of the periodic table, such as silicon, phosphorus, and sulfur
- Cross-coupling reaction
- A reaction that efficiently joins different carbon compounds together. It has also been recognized with a Nobel Prize
- Transition metal
- Metal elements in the middle of the periodic table. Palladium and rhodium are rare examples that make excellent catalysts

ResearchResearch themes
The lab aims to build the foundation of "all-element organic chemistry," which looks across the whole periodic table and brings out the "individuality" of each element to the fullest. To this end, it investigates the properties of compounds of heavier main-group elements such as silicon and phosphorus, and works on developing new functions and catalytic reactions.
*Illustrative imageCompounds of Heavier Main-Group Elements
The lab synthesizes compounds in which elements such as carbon and nitrogen are replaced by elements of the third period and beyond, such as silicon, phosphorus, and sulfur, and examines their properties in detail. By identifying the differences from organic compounds, it extracts the characteristics of the elements and uses them to explore new functions and properties.
*Illustrative imageRedox Systems of Main-Group Elements
Using bulky ferrocenyl substituents that the lab developed itself, it synthesizes compounds of silicon, germanium, tin, phosphorus, antimony, and other elements that normally cannot be isolated, and studies their oxidation and reduction behavior. The aim is to create substances that readily accept and donate electrons.
*Illustrative imageDevelopment of Catalysts Without Transition Metals
Excellent catalysts for cross-coupling reactions require rare transition metals such as palladium and rhodium. The lab makes use of the characteristics of heavier main-group elements to develop new catalysts for small-molecule transformation reactions that do not use these metals. It aims for catalysts based on abundant elements such as silicon and aluminum.
