AI Article Synopsis
- The study focuses on modifying the properties of the arsenic transfer reagent [Cp″Zr(η-As)] to expand its reactivity.
- Different Lewis acids and their steric requirements influence the synthesis of various new complexes with unique coordination modes and numbers based on experimental and computational analysis.
- The research highlights how the As ligand can rearrange into different coordination forms, such as η and -As, and discusses these changes in terms of inverse coordination concepts.
Article Abstract
The functionalization of the arsenic transfer reagent [Cp″Zr(η-As)] () focuses on modifying its properties and enabling a broader scope of reactivity. The coordination behavior of towards different Lewis-acidic transition metal complexes and main group compounds is investigated by experimental and computational studies. Depending on the steric requirements of the Lewis acids and the reaction temperature, a variety of new complexes with different coordination modes and coordination numbers could be synthesized. Depending on the Lewis acid (LA) used, a mono-substitution in [Cp″Zr(µ,η-As)(LA)] (LA = Fe(CO) (); B(CF) ()) and [Cp″Zr(µ,η-As)(Fe(CO))] () or a di-substitution [Cp″Zr(µ,η-As)(LA)] (LA = W(CO) (); CpMn(CO) (); AlR (, R = Me, Et, Bu)) are monitored. In contrast to other coordination products, shows an η coordination in which the butterfly As ligand is rearranged to a -As ligand. The reported complexes are rationalized in terms of inverse coordination.
