Redox Properties of Pyrene-Cyclohexene Conjugates – Electrochemical Study
 Koláčná, Lucie ; Čubiňák, M. ; Tobrman, T. ; Ludvík, Jiří
The series of 16 compounds for "organic electronics" comprising the double-bond cyclohexene core extended by pyrene and/or other aromatics were electrochemically characterized by rotating disk voltammetry in N,N-dimethylformamide. Due to multiple substitutions, the resulting potential gap represents the sum of all substituent effects. Different combinations of substituents can be used to achieve the desired properties of cyclohexene-pyrene derivatives. The electrochemical data presented in this contribution facilitate further tuning of properties of these molecules and systems to achieve features required in material chemistry just by means of chemical modification.

Acylation of cyclohexene can provide number of reaction products. Cyclohexene, 1-methylcyclohexene and 3-methylcyclohexene were acylated with propionic anhydride over diferent zeolite structures and molecular sieves. Cyclohexene acylation led to propionylcyclohexene. The major acylation products of 1-methylcyclohexene is 2-methyl-3-propionylcyclohexene. Reaction product of 3-methylcyclohexene acylation is 4-methyl-3-propionylcyklohexene and 3-methyl-2-propionylcyclohexene. The aim of acylation biphenyl with carboxylic acid anhydrides and chlorides was to prove reaction with the highest conversion of substrate. The highest biphenyl conversion was obtained with octanoyl chloride and hexanoic anhydride over zeolite USY (15). The highest selectivity to 4-acylbiphenyl was observed.
