Synthesis of tricyclic hydrocarbon derivatives
Tuzova, Uliana ; Hrdina, Radim (advisor) ; Rýček, Lukáš (referee)
This bachelor thesis deals with the preparation of enantiopure Binol-derived phosphoric acids with different substituents at the 3,3'-position, which are typically used as Brønsted acids in enantioselective non-covalent organocatalysis. The prepared 3,3'-adamantane substituted Binol-derived phosphoric acids are planned to be used as organocatalysts. Bulky alkyl substituents at the 3,3' position have been introduced in order to compare their properties with those of phenyl substituents at the 3,3' position. The different dispersion forces between substrate and catalyst are expected when aryl and alkyl substituents are incorporated into the catalyst structure. Keywords Organocatalysis, asymmetric synthesis, Brønsted acids.

The catalysts with various Mn content were examined by XRD, SEM, FUR. XPS, and Ih-TPR. tested in the gas-phase oxidation of model organic compound (ethanol) and compared with pelletized commercial Co-Mn- Al mixed oxide catalyst (Astin 2-100, Czech Republic, Co:Mn:Al molar ratio of 4:1:1 ).
