    摘要: New compounds useful as constituents of liquid crystal compositions exhibiting a negative dielectric anisotropy are provided, which are 2-cyano-4-halogenophenyl esters expressed by the general formula ##STR1## wherein R represents hydrogen atom or an alkyl group or an alkoxy group of 1 to 10 carbon atoms; ##STR2## each represent either one of ##STR3## l, m and n each represent 0 or 1 and the total of l+m+n is 1, 2 or 3; X represents F or Cl; and Y and Z each represent hydrogen atom or F or Cl.
