Inventor: ITSUKIDA NOBORU
IPC: G02F1/13
Filed: 1981-11-20
Abstract: PURPOSE:To prepare the titled compound in high yield, without causing side reactions nor necessitating purification process, by using N-(4-substituted-benzamido)-triphenylphosphinium bromide as a raw material, and subjecting the material successively to the heating process, dehydrobrominating process and dehydrogenating process. CONSTITUTION:N-(4-Substituted-benzamido)-triphenylphosphinium bromide is heated, e.g. at 100 deg.C and then dehydrobrominated. The resultant product is then dehydrogenated to obtain the symmetrical tetrazine-type nematic liquid crystal substance of formulaI, formula II or formula III (R is CnH2n+1- or CnH2n+1O-; n is 1-10). The above starting compound can be prepared by reacting triphenylphosphine dibromide with a 4-substituted benzhydrazide in the presence of triethylamine.
