MMA Polymerization with Group 4 Alkyl-Free 14-Electron d0 Species
Cationic 1,2 and 1,3 doubly constrained geometry di(silylamido)cyclopentadienyl zirconium complexes, whilst being group 4 alkyl-free 14-electron d0 species, promote the polymerization of MMA. Different cocatalysts such as B(C6F5

Evidence of fluoride transfer from the anion of [Zr{C5H 3[SiMe2(η1-NtBu)]2}] +[RB(C6F5)3]- complexes to the zirconocenium cation
(Chemical Equation Presented) C-F bond activation: In the presence of a phosphane, deactivation of cationic zirconium complexes can occur by direct fluoride migration to the zirconium center, that is, the breaking of a C-F bond - the strongest bond of organic molecules - without previous C6F 5 transfer to the metal atom (see picture).
