PURPOSE: To obtain the subject substance by reacting an aromatic compound with 1,1,1,3-tetrachloropropane or 1,1,1-trichloro-2- or 1,1,3-trichloro-1-propene in the presence of a Friedel-Crafts catalyst. n CONSTITUTION: A compound of formula I and/or formula II (Ar 1 and Ar 2 are each an aryl that may be substituted) is reacted with a compound of formula III or formula IV (R 1 is H, a 1-18C alkyl; R 2 is H or 1-18C alkyl that may be substituted), etc., at -20 to 150°C in the presence of a Friedel-Crafts catalyst (example: AlCl 3 or BF 3 ) in a liquid phase or at 200-450°C in a gas phase to obtain a compound (including new substances) of formula V (n is integer of 0-5; Ar 1.2 is Ar 1 or Ar 2 ). When the reaction is carried out in two steps, 1,1,1- trichloro-3-methyl-3-phenylbutane, etc., produced in the process are new substances. A compound of formula V is useful as a raw material of polyimide, etc. n COPYRIGHT: (C)1991,JPO |
