Abstract:4-(Trans-4'-n-alkyl cyclohexyl)cyclohexylformaldehydes which were used as ethane- and ethylence-type liquid crystal intermediates were synthesized in “one-pot” reaction from 4-(trans-4'-n-alkyl cyclohexyl) cyclohexyl methoxymethene through hydrolysis and isomerization. The overall yield of the product after purification was about 75%. |
Key words:hydrolysis;isomerization;“one-pot” |
