    • Disclosed are: an advantageous production process for a carotenoid intermediate; and others. Specifically disclosed are: a process for producing a dialcohol represented by formula (1), which is characterized by reacting a Grignard reagent with an acetylene gas in an organic solvent at a temperature of 30°C or higher to prepare an ethynyl magnesium halide and subsequently reacting the ethynyl magnesium halide with methacrolein; a process for producing an allylhalide compound represented by formula (3) [wherein X represents a halogen atom: and the wavy line means the compound is either of E/Z geometric isomers or a mixture thereof], which is characterized by reducing a dialcohol represented by formula (1) with hydrogen to produce a triene alcohol represented by formula (2) [wherein the wavy line is as defined above] and halogenating the triene alcohol; and an allylchloride compound represented by formula (4) [wherein the wavy line is as defined above].

    • The present invention relates to a process for preparing fluorinated conjugated olefinic products having, among others, the formulae:

      wherein:
      R x and R y       represent, among others, perhaloalkyl radicals containing from 1 to 10 carbon atoms (in the case of R x ) and from 1 to 9 carbon atoms (in the case of R y ), and
      m      ranges from 2 to 10.
      These olefinic products are obtained by reacting telomeric products having, among others, the formulae:
      R x O-(CFCl-CFCl) m -F
      R x O-(CFCl-CFCl) m -OR x
      F-(CFCl-CFCl) m -F and
      R y -(CFCl-CFCl) m -F
      with zinc powder at temperatures of from about 40°C to about 160°C and in a solvent selected from alcohols, dimethylformamide and dimethylsulfoxide.
      Many of the resulting products are new.
