, p. 259 - 268 (2019/06/19)
Five new chemo-receptors, based on arylamino-naphthoquinone, possessing electron donating and electron withdrawing substituents have been prepared by single step green method. These receptors are found to be highly selective and sensitive towards cyanide
Composition for Distructing Microalgae
-
Paragraph 0469-0472, (2017/09/05)
The present invention relates to a composition for destroying microalgae, more specifically, to a composition for destroying microalgae containing naphthoquinone compounds having a specific exchange group. The composition for destroying microalgae, according to the present invention, can prevent green tide and red tide by being processed in areas such as cultivation facilities for microalgae, areas in which the green tide or the red tide occur, or areas expected to occur the green tide or the red tide.
Charge transfer facilitated direct electrophilic substitution in phenylaminonaphthoquinones: Experimental, theoretical and electrochemical studies

Reactions of bis-benzalethylenediamine (1), N,N'-bis(aryl)- and N,N'-bis(cyclohexyl)ethane-1,2-diylidenediamines as well as N,N'-bis(aryl)benzene-1,4-diyldimethylidenediamines 2 with benzo- and naphthoquinones as well as α,β-unsaturated ketones such as 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ); 2,3,5,6-tetrachloro-1,4-benzoquinone (CHl-p); 3,4,5,6-tetrachloro-1,2-benzoquinone (CHl-o); 2,3-dichloro-1,4-naphthoquinone (DCNQ); 2,3-dicyano- l,4-naphthoquinone (DCNQ) and dicyanomethyleneindane-1,3-dione (CNIND) afforded quinoxaline, pyrazinoquinoxaline, imidazolidine, indole and carbazole derivatives as well as arylaminobenzo-, and napthoquinones.
Iodination and chlorination of 2-/4-arylamino-1,4-/1,2-naphthoquinones with alkylhalides and DMSO
Kallmayer,Doerr
, p. 479 - 485 (2007/10/03)
2-/4-Arylamino-1,4-/1,2-naphthoquinones 10/13 are chlorinated with tert-butylbromide, DMSO and calcium chloride to give 2-/4-arylamino-3-chloro-1,4-/1,2-naphthoquinones 11A/14A. The iodination with tert-butylbromide, DMSO and potassium iodide give 2-/4-arylamino-3-iodo-1,4-/1,2-naphthoquinones 11C/14C.
