    摘要： NEW MATERIAL:A fluorine-containing amide compound expressed by formula I (R1 and R2 are H or 1-30C alkyl which may have a branched chain). EXAMPLE:A compound expressed by formula II. USE:Useful especially as a surface modifier for high polymers and also as a sliding agent for surfaces in contact with metal and further as a metal surface treating agent, water and oil repellent, etc. PREPARATION:A benzenemonocarboxylic acid or benzenedicarboxylic acid having perfluorononeyloxy group as a starting raw material is reacted with thionyl chloride, etc., and converted into an acid chloride, which is then reacted and amidated with various amines in the presence of a base, such as triethylamine, in a solvent, such as diethyl ether, to afford the compound expressed by formula I.

    摘要： PURPOSE:To obtain a high nonlinear optical effect by using a specific compd. so that inverse symmetry is hardly obtainable in a bulk state such as crystal or thin film and the material has substantially no absorption in a visible region. CONSTITUTION:The compd. expressed by formula I is used as this material. In formula I, D denotes an electron-donating group; C denotes a monovalent org. group; R denotes a hydrogen atom, alkyl group, aryl group or heterocyclic group; (m) denotes 1-3 integer; (n) denotes 0-3 integer. This compd. is usable as the nonlinear optical material in various forms such as single crystal, powder, soln. the thin film (Langmuir-Blodgett film, vapor deposited film, etc.) deposited on a base or the form of blending the same into a polymer or liquid crystal molecules. The material which has substantially no absorption in the visible region is obtd. and the inverse symmetry is hardly obtainable in the form of use. In addition, high second harmonic waves are generatable.

    摘要： NEW MATERIAL:A compound expressed by formula I [X is H, Cl or F; Y is H or NO2; Z is formula V (Q is CN, carboxyl or carboxylic acid derivative), formula VI (R is H, lower alkyl, lower alkenyl, lower alkynyl, cycloalkyl, aralkyl, alkoxyalkyl or alkali metal, e.g. Na or K, etc.]. EXAMPLE:3-(2-Chloro-4-trifluoromethylphenoxy)-alpha,alpha-dimethylphen ylacetonitrile. USE:A herbicide suitable for controlling weds growing in paddy field, upland field, orchard and uncultivated land. PREPARATION:A compound expressed by formula II is reacted with a halogenating agent in the presence of a radical reaction initiator to form a compound expressed by formula III (hal is Cl or Br), which is then reacted with NaCN to give a compound expressed by formula IV. The resultant compound expressed by formula IV is then reacted with CH3I in the presence of a base to afford the aimed compound expressed by formula I [Y is H; Z is formula V (Q is CN)].
