A research group, consisting of Associate Professor Hajime Kameo and Professor Hiroyuki Matsuzaka at the Graduate School of Science of Osaka Prefecture University and Professor Didier Bourissou at Université Toulouse III – Paul Sabatier, has succeeded, for the first time in the world, in catalytically converting fluorosilane, which is thought to be the strongest silicon-fluorine bond, by using the synergism effect of a palladium or nickel molecular catalyst and Lewis acid as the key.

Characteristically, silicon forms a strong bond with an electronegative atom such as fluorine. For this reason, silicon compounds are used for applications that require high durability and high thermostability, including semiconductors and materials for medical use. Meanwhile, due to the lack of technologies that can convert a strong silicon-fluorine bond, recycling has been considered difficult. This technology, which converts the strongest silicon-fluorine bond, is expected to be applied to silicon compound recycling technology, and it also provides basic technology for creating their recycling system.

The results of this research were published and highlighted as a cover picture in the preliminary online version of Journal of the American Chemical Society on July 24, 2020.
