Novel trans hydrocarbon compound

Abstract

Abstract NEW MATERIAL:A compound expressed by formula I (R and R' each are independently 1-5C straight chain alkyl). EXAMPLE:A compound expressed by formula VII. USE:An electrooptical display material, suitable for preparing high-speed response mixed liquid crystals useful for mounted displays, etc., and capable of exhibiting improved characteristics of reducing viscosity without lowering DELTAn when mixed with various matrix liquid crystals. PREPARATION:A 4-n-alkylbenzene is reacted with a compound expressed by formula II to give a compound expressed by formula III, which is then reduced to afford a compound expressed by formula IV. The resultant compound expressed by formula IV is then dehydrated under heating to give a compound expressed by formula V, and bromine is then added thereto to afford a compound expressed by formula VI, which is finally reacted with a base, e.g. 1,5-diazabicyclo [5.4.0]undecene-5 to afford the aimed compound expressed by formula I.
