    摘要： PURPOSE: To provide a novel organic fluorine compound which is excellent in resistance to solvents and chemicals and useful as a starting substance for rubber materials, water-repellent and oil-repellent agents and release agents. CONSTITUTION: This organic fluorine compound is expressed by formula I (R f is a divalent perfluoroalkylene, a divalent perfluoropolyether; R f is a monovalent perfluoroalkyl, perfluoroalkyl ether; n is an integer of 1-5), for example, a polymer of an organic fluorine compound of formula II (m+n=35). The compound of formula I is obtained, for example, by reaction of a compound bearing acid fluoride groups on both chain terminals of formula III with a fluorine- containing allylamine of formula IV in the presence of an acid acceptor.

    摘要： PURPOSE:To obtain a new derivative useful as a herbicide, having high selective herbicidal activity especially against barnyard grass by reacting a styrene derivative with a polyhaloalkane in the presence of a metal salt and an amine compound. CONSTITUTION:(A) A styrene derivative of formula I (A is a group of formula II or formula III) is reacted with (B) a polyhaloalkane of the formula CCl2XX' (X is a halogen or 1 1-4C haloalkyl; X' is Cl or Br) (preferable example: bromotrichloromethane) in the presence of a metal salt preferably composed of a copper salt of a hydrohalogenic acid or a copper salt of oxyacid and an amine compound preferably composed of an aliphatic primary amine, cyclohexylamine or piperidine to give a derivative of formula IV. 3-Methyl- N-[3-(1,1,1,-trichloro-3-buten-3-yl)benzyl]acetamide may be cited as the derivative.

    摘要： PURPOSE:To provide a novel brominated acetylene which is useful in the synthesis of diacetylenes giving isotropic high toughness material or as an intermediate for chemical modification of amides. CONSTITUTION:A brominated acetylene of formula I (R2 is a hydrocarbon having unsaturated bonds such as H2C=CH-, formula II, formula III; X is an organic group of 1 to 13 carbon atoms, for example, -CH2-, formula IV). The brominated acetylene of formula I is obtained, for example, by subjecting a carboxylic acid of the formula: R2-COOH or an acid chloride of the formula: R2-COCl and an acetylenic amino compound of formula V to dehydration or dehydrochlorination to prepare an acetylene amide of formula VI and by allowing the product to react with NaOBr. The brominated acetylene is a very important intermediate for synthesis of unknown diacetylenes of a new type having unsaturated bonds by utilizing the reactivity of the terminal bromine. The crosslinked products show excellent heat resistance.
