摘要
以4-(3,4-二氟苯基)-环己基酮和单新戊二醇缩-4,4′-双环己二酮为起始原料,通过合成关键中间体反式-3,4二氟苯基环己基甲基碘三苯基膦盐和4-(反式-4-乙烯基环己基)环己基甲醛,制备了液晶单体反-4-(2-(4-(3,4-二氟苯基)环己基)乙烯基)-4′-乙烯基双环己烷,采用1HNMR和MS手段对其结构进行了表征,并对工艺进行了优化.
As the excellent performance of diolefin fluorous liquid crystal compound,（E）-4-（trans-4-（2-（trans-4-vinylbicyclohexyl）vinyl）cyclohexyl）-3′,4′-difluorophenyl was synthesis from 4-（3,4-difluorophenyl）cyclohexanone,1,4-cyclohexanedione monoethylene acetal,and bicyclohexane-4,4′-dione momo-neopentylketal using a series classical organic reactions,which was confirmed by 1HNMR and MS.The key intermedia trans-4-（3′,4′-difluorophenyl-4-yl） cyclohexylmethyltriphenyl-phosphonium iodine and trans-4-vinylbicyclohexanecarbaldehyde were prepared.
