Arnaud Osi is a PhD. student, he obtained is bachelor degree in the University of Namur, Belgium, in 2017 and is Master degree in 2019 under supervision of Prof. Guillaume Berionni. He obtained the FRIA grand and started to work on his thesis in November 2019 in organic chemistry under the supervision of Prof. Guillaume Berionni. The first part of his thesis is dedicated to the synthesis of the boratriptycene and derivatives in order to develop strong Lewis acids while the second part aims for C-F activation using strong Lewis acids.
