Abstract: PURPOSE:To provide a simple process for the production of a fluorine-containing compound useful as an important raw material for pharmaceuticals, agrochemicals, functional materials, etc. CONSTITUTION:This process for the production of a fluorine-containing compound expressed by the general formula Y-CF2-CR2-CR2-R' or R'-CR2-CR2-(CF2)n- CR2-CR2-R' comprises the reaction of an organotin compound expressed by the general formula R'SnR''3 with a halogenated compound expressed by the general formula Y-CF2-CR2-CR2-X or X-CR2-CR2-(CF2)n-CR2-CR2-X (R' IS alkenyl, alkynyl, aralkyl or aromatic group; R'' is alkyl; Y is H, halogen or polyfluoroalkyl; X is halogen; R is H, alkyl, alkenyl, alkynyl or aromatic group; (n) is integer of 1-20).

Abstract: PURPOSE:To produce a fluorocopolymer useful as a water-repellent polymer or a main chain type high-molecular liquid crystal polymer by reacting a specified fluoroalkyl halide with an organic halide and metallic magnesium in the presence of a metal catalyst. CONSTITUTION:A fluoroalkyl halide of formula I (wherein X is I or Br; R is H, alkyl, alkenyl, alkynyl, an aromatic group, provided that two Rs may be suitably combined with each other to form a ring together with the carbon atoms to which they are bonded; and n is 1-20) is reacted with an organic halide of formula II (wherein Y is I, Br or Cl; and R' is an aromatic group of an atomic group composed of a plurality of aromatic groups bonded with each other directly or through bonding groups) and metallic magnesium to obtain a fluorocopolymer comprising repeating units of formula III (wherein R and n are each as defined above). This copolymer shows excellent water repellency and has liquid crystal properties over a wide range of temperature.
