Synthesis of Highly Substituted 2-13C-Imidazolium Salts and Metal NHC Complexes for the Investigation of Electronic Unsymmetry by NMR
摘要:
Complexes of unsymmetrically substituted N-heterocyclic carbenes with NMR-active metals (Ag, Hg, Pt) with or without a C-13-label in the 2-position were synthesized by aldimine cross coupling and analyzed with respect to the scalar couplings between the metal center or C2 and the other ring atoms.
