    摘要： The present invention provides a difluoromethyl ether derivative which shows various suitable physical properties as a liquid crystal compound, a liquid crystal composition comprising the compound and a liquid crystal display element containing the composition, and also provides a simple and efficient process for producing the difluoromethyl ether derivative. According to the present invention, a process for producing a difluoromethyl ether derivative represented by Formula (1d): 1 wherein the variables are defined in the specification, is characterized by using an nullnull-difluorocyclohexylidene derivative represented by Formula (1a): 2 wherein R1, rings A1 and A2, Z1, Z2, k and l have the same meanings as defined in the specification, as a starting material. fluorine, a cyano group or an alkyl group having 1 to 10 carbon atoms; Z1, Z2, Z3 and Z4 each independently represent a single bond or an alkylene group having 1 to 4 carbon atoms, in which at least one nullCH2null may be substituted with nullOnull, nullSnull, nullCHnullCHnull or nullCnullCnull but nullOnull is not adjacent to another nullOnull, and in which any hydrogen may be substituted with fluorine; Y1, Y2, Y3 and Y4 each independently represent hydrogen, halogen, a cyano group or an alkyl group having 1 to 10 carbon atoms; and k, l, m and n each independently represent 0 or 1; is characterized by using an null,null-difluorocyclohexylidene derivative represented by Formula (1a): 3 wherein R1, rings A1 and A2, Z1, Z2, k and l have the same meanings as defined above; as a starting material.
