Four more pyridazine compounds were synthesized.The compounds have a general structure R-X-Y-Z-R'; where Y is 3,6 disubstituted pyridazine ring, X and Z are either trans cyclohexyl or phenyl rings, R and R' are n-alkyl groups.The structure assignments were confirmed by carbon 13 NMR.Their liquid crystalline properties were evaluated.When both X and Z are cyclohexyl rings, the compounds have a single smectic b phase.However, if a phenyl ring is introduced into the system, the morphology becomes complicated.Keywords: synthesis, pyridazine, smectic, classification

The cyclization of trans-1-acrylyl-4-n-alkylcyclohexanes with trans-1-N-piperidino-1-alkenes was used to synthesize 3-n-alkyl-6-(trans-4-n-alkyl-cyclohexyl)-3,4-dihydro-2-N-piperidino-2H-pyrans, which were converted under the influence of hydroxylamine to 5-n-alkyl-2-(trans-4-n-alkylcyclohexyl)-pyridines.Problems in the stereochemistry of the cyclohexane derivatives in the investigated scheme of synthesis were examined.
