Prof. Dr. Shigeyoshi Inoue (TU München): N-Heterocyclic Carbenes and N-Heterocyclic Imines as Ligands in Reactive Main Group Metal Complexes

AC Kolloquium
Referent/in: Prof. Dr. Shigeyoshi Inoue
Inhalt:

N-heterocyclic carbenes (NHCs) have received a great deal of attention and have now been employed in a broad range of fields. For example, they have been employed as versatile ligands for transition metals, main group elements, even lanthanides and actinides. Also, the application of NHCs in organocatalysis has been proven as an attractive metal-free method to synthesize a variety of important species. On the other hand, N-heterocyclic imines (NHIs), namely, imidazolin-2-imino group that derived from the class of compounds known as guanidines, are structurally related to NHCs. NHIs are strong σ- and π-electron donors, a feature borne of the allocation of positive charge density from the exocyclic imino group into the imidazoline ring. The steric bulk of N-heterocyclic imines can easily be modified as required for kinetic stabilization of a target main group compound. This presentation will focus on the synthesis and structure of novel low-valent main group compounds (B, Al, Si, Ge and Sn) stabilized by NHIs and NHCs as support ligands and their interesting reactivity as well as catalytic applications. Within this, selected example of compounds with main group elements stabilized by NHIs and/or NHCs will be presented.
