The course in planned in theoretical (6 CFU, 48 hours) and experimental (3 CFU, 48 hours) lessons. The theoretical part deals with the general properties of organometallic complexes which are classified considering the nature of coordinated ligands. The course provides: i) general syntheses of organometallic complexes; ii) physical and chemical properties of organometallic complexes; iii) chemical reactions in which organometallic complexes are involved (oxidative addition and reductive elimination; insertion and elimination, nucleophilic and electrophilic addition and abstraction; iv) introduction to the homogeneous catalysis. The course also deals with the synthesis and characterisation of coordination complexes. The laboratory work focuses on some subjects illustrated during theoretical lectures: i) template synthesis; ii) synthesis of metal hydride complexes; iii) O2 activation; iv) substitution reactions; v) oxidative addition. During a pre-laboratory lecture practical and theoretical aspects of all the synthesis will be given. The synthesis of air-sensitive complexes is performed under inert atmosphere using Schlenk technique (vacuum/nitrogen). Students will use combined N2-vacuum line and special glassware.
