Pyrazine Carbonyl Compounds - Building Blocks in Dynamic Combinatorial Systems
Coufal, Radek ; Drahoňovský, Dušan (advisor) ; Jindřich, Jindřich (referee)
This bachelor thesis deals with the synthesis of bifunctional carbonyl derivatives of pyrazine, which are further examined for their potential to form dynamic hemiacetals with monofunctional alcohols. Newly prepared, in the literature not yet described bifunctional trifluormethyl derivatives exhibit considerable ability to form hemiacetals in a dynamic system. The obtained results show that these substances may find application as building blocks of dynamic combinatorial systems.

Dynamers based on the reversible formation of hemiacetals
Nosek, Vladimír ; Drahoňovský, Dušan (advisor) ; Míšek, Jiří (referee)
This work deals with the design and synthesis of building blocks, usable for creating dynamic polymers based on the reversible formation of hemiacetals bond. Next part is focused on the study of the formation of hemiacetal between polyfunctional alcohols and trifluoromethylketones via NMR spectroscopy. Key words: constitutional dynamic chemistry, hemiacetals, trifluoromethylketones, diols and polyols

Preparation of fluorophilic building blocks for constitutional dynamic systems
Kretschmer, Jan ; Drahoňovský, Dušan (advisor) ; Jindřich, Jindřich (referee)
Perfluoralkylated and trifluormethylated aromatic benzylamines and benzaldehydes were prepared. The compounds were used for Schiff bases sythesis. Future observations with these compounds are planned. The Observations are going to be focused on imine-bond formation and phenomenon of fluorophilicity. Specifically, if fluorophilicity can affect selection of reacting partner in imine-bond formation. This observation could be useful for understanding how fluorophilicity can affect formation of dynamic combinatorial libraries. Powered by TCPDF (www.tcpdf.org)
