Title: Synthesis and characterization of bidentate P,N-donor ferrocene ligand Author: Bc. David Rezazgui Department: Department of Inorganic chemistry Supervisor: RNDr. Jiří Schulz, Ph.D. The main goal of this thesis was the preparation and characterization of ferrocene ligand 4-[1'-(diphenylphosphino)ferrocen-1-yl]morpholine (compound 3). Compared to structurally similar compounds, compound 3 offers greater geometrical flexibility which might have a positive effect in some applications, for example in catalysis by transition metal complexes. Two new compounds were synthesized along the synthetic route of phosphinoamine 3, the protected amine 1 and morpholine derivate 2. Selenide 4 was prepared in order to determine the basicity of compound 3 via the direct scalar interaction of 77 Se with 31 P. The synthesis comprised phosphinylation of 1,1'-dibromoferrocene, protection of the obtained 1-bromo-1'- (diphenylphosphino)ferrocene with sulfur, azidation and immediate reduction to protected amine 1. Morpholine derivate 2 was subsequently synthesized by cyclization reaction with bis(2-chloroethyl)ether. Phosphinoamine 3 was obtained by deprotection of compound 2 with Raney nickel. Finally, selenide 4 was obtained by the reaction of 3 with KSeCN. All newly prepared compounds were analyzed by NMR and transmission...
