Organometallic Fluorine Chemistry: New Reactions and Mechanisms
Organometallic fluorine chemistry has received considerable attention during the last decade. Particularly, electrophilic fluorination of organometallic platinum group complexes has emerged as a powerful tool to introduce various functions into organic compounds.1 In this talk, I will present our results on the formation of C-C, C-X (X= F, I) and I-F bonds under the electrophilic fluorination conditions. I will also discuss mechanistic requirements for the reductive elimination of carbon-halogen bonds taking place under the kinetic conditions.
In the second part of my talk, I will present our latest studies of the new pincer ligand system bearing fluorine atom as a side arm. In particular, I will discuss the reactions leading to stoichiometric and catalytic activation of O-H, N-H, S-H and C-H bonds that involve reversible dearomatization-aromatization of the ligand’s aromatic core.2
