Reactions of Alkenes Iniciated by Transition Metals Alkyls and Hydrides David Nečas Department of Organic and Nuclear Chemistry, Faculty of Science, Charles University, Hlavova 8, 128 40 Prague 2, Czech Republic. Keywords: C-C bond cleavage, C-C bond formation, Nickel, catalysis The C-C bond activation (cleavage) as well as the C-C bond formation under mild and simple reaction conditions are intensively sought after processes. In the course of this thesis new nickel based catalytic system was found suitable for formation of C-C bonds (cyclization of α,ω-dienes) and for cleavage of unactivated C-C bonds in allyl malonates and related compounds. Mechanistic and structural aspects of these reactions are also discussed as well as a relation of C-C bond formation (cyclization) to the C-C bond cleavage (deallylation). This work was supported by FRVŠ No. 42-202755, MŠMT No. 1M0508 Centre for New Antivirals and Antineoplastics, MŠMT No. LC 06070 Center for Structural and Synthetic Application of Transition Metal Complexes and is a part of the Research Project MSM0021620857.
