| Abstract: | The synthesis and X-ray structures of gold(I) adducts supported by beta-diketiminates have been reported. {[HC{(H)C(2,4,6-Br(3)C(6)H(2))N}(2)]Au}(2) and {[HC{(H)C(Dipp)N}(2)]Au}(2) [Dipp = 2,6-(i-Pr)(2)C(6)H(3)] are easily isolable solids and feature 12-membered macrocyclic ring structures. beta-Diketiminate ligands adopt a W-shaped conformation. Gold atoms are bonded to the nitrogen atoms in a linear fashion. (1)H NMR signals corresponding to the protons at the beta-diketiminate ligand beta-C position of the gold adducts appear at a notably high downfield region. |
