Compounds 112 were synthesized by using 6-alkyl-2-decalone as raw material and through reactions of corresponding carbonyl compounds with Grignard reagent, dehydration, reduction and isomerization. Yields from 9.9% to 80.8% were got and those of compounds 2 and 3 are higher than the reported data. Structures of the products have been identified by IR, 13C NMR and MS spectra, and their phase transition behaviors were measured by DSC. Using base as catalyst, isomerization mechanism among decalin derivatives was also studied.

Key words: liquid crystal, synthesis, configuration, phase transition temperature, trans-decalin
