dc.description.abstractAs an alternative for transition metal (TM) catalysis, main group elementshave merged. Recent studies demonstrate that various low-valence maingroup elements have significant potential to become an effective alternativeto traditionally used transition metal compounds. Among these species,carbenes and their analogs, which possess a small HOMO-LUMO gap andfrontier orbitals similar to those of transition metals, are promising candidatesto replace transition metal complexes. Thus, initially, a chloroplumbylene hasbeen synthesized from the iminophosphine ligand. The Pb(II) cation stabilizedby phosphine, generated by the abstraction of chloride fromchloroplumbylene, is strongly electrophilic and requires a second Lewis base(L = phosphines or amines) for stabilization, forming donor-acceptorcomplexes with them. Of particular interest, the stable cationic Pb(II) complexwith a secondary amine can be used as a catalyst for the hydroamination ofphenylacetylene (chapter 2,).In the same vein, this chapter (chapter 3) presents the synthesis and of analuminum(I) species stabilized with the same substituent in addition to thecoordination of an additional Lewis base. The tricoordinated aluminum(I)complex is highly nucleophilic and reactive. Notably, this complex canactivate C-C bonds.
