Title: Synthesis of gold(I) biscarbene complexes with ferrocenyl substituents Author: Bc. Michal Franc Institution: Faculty of Science, Charles University in Prague, Department of Inorganic Chemistry Supervisor: prof. RNDr. Petr Štěpnička, Ph.D., DSc. Abstract: Coordination-activated isocyanides attracted attention after it was found that carbene complexes could be readily prepared from them by addition reactions of protic nucleophiles. Carbenes have attracted much interest in recent years as a new class of ligands for transition metals and catalysis. Their advantage is their ability to stabilize catalytically active centers and thereby accelerate catalytic processes. This work presents the preparation of biscarbene gold(I) complexes with ferrocene substituents via addition reactions of amines. The starting material was a bis(isocyanoferrocene)gold chloride, which was the reaction of amines to Fischer-type protic carbenes by reactions with amines. Further, bis(isocyanoferrocene)gold(I) perchlorate was prepared and from it bis(isocyanoferrocene)gold(I) complex was synthesised by addition reaction of mofoline. All newly prepared compounds (Scheme 1), except compound 1, were characterized by NMR (except insoluble compound 5), IR spectroscopy, elemental analysis, MS and their solid state structure was...
