    Abstract: PURPOSE:To provide the subject compound useful for nonlinear optical materials exhibiting high nonlinearity, etc., by addition-reacting thiophenol, a nitroalkane, etc., to an unsaturated aldehyde, subjecting the addition product to dehydration and dehydrogenation reactions to form a butadiene structure, and respectively substituting the product with an amino structure. CONSTITUTION:An alpha, beta-unsaturated aldehyde of formula I (R , R are H, alkyl) or formula II (e.g. acrolein) is dissolved in tetrahydrofuran, addition-reacted to a compound of the formula Ar-ZH (Ar is aromatic; Z is S, Se, Te) (e.g. thiophenol) for 2-3hrs with cooling and stirring, and subsequently mixed with a nitroalkane (e.g. nitroethane). The reaction product is addition-reacted with the formyl group of an,-unsaturated aldehyde, and subjected to a dehydration reaction and a dehydrogenation reaction to form a butadiene structure. The Ar-Z group of the reaction product is substituted with an amino group to afford the objective nitrobutadiene compound represented by the formula III [R , R ' are alkyl, group of formula IV (R , R are H, hydrocarbon, etc.,); R , R are alkyl, nitro, H].

    Abstract: PURPOSE:When anthraquinone is nitrated in the presence of a halogenated aliphatic hydrocarbon to produce the titled compound, a small amount of anthrone is made to coexist to make the particle size of the product uniform, thus facilitating the purification and separation and increasing the yield. CONSTITUTION:Anthraquinone is nitrated with a mixed acid in the presence of a halogenated aliphatic hydrocarbon such as methylene chloride, using high-concentration sulfuric acid, preferably of 80-95%, in an amount of 1.5-7.0, preferably 2.0-4.0 times the weight of the anthraquinone, and anthrone in an amount of 0.002-0.05, preferably 0.004-0.02pt. per 1pt. of the antraquinone to given 1-nitroanthraquinone. The reaction temperature is 0-60, preferably 10- 45 deg.C. An example of the halogenated aliphatic hydrocarbon is methylene chloride or 1,2-dichloroethane.
