Description:
This project deals with the preparation of hybrid ligands suitable to stabilize d- and f-block as well as the main group metal centers in generally low oxidation states. The ligands are proposed to be the hybrid aminocarbenes, amidinates and guanidinates with adjacent coordinating group, thiaamidinates, boraamidinates, amido-amidinates or guanidinates and other derivatives of macrocyclic ligands. The metals of interest are the environmentally friendly Ca, Zn, Al, Fe, Zr, Bi and Cu, and metals with a high potential in homogenous catalysis and material applications as for example Ge, Sn, Sc, Y, La, Au, Pt, Pd, Rh, Ru, Ce, Sm, Yb and others. The stabilization of respective organometallic compounds or complexes in unusual, and often obscure, low oxidation states will be evaluated and the activity in important chemical processes tested. A quest for compounds with metals in lower oxidation state (also radical and biradicalloid species) than is usual as for example Ca(I), Zn(I), Au(0), Bi(I and II), Al(I and II) Si(I, II and III; also for Ge, Sn and Pb) etc. will be performed.
