چکیده
|
The solid–solid reactions of electron-donor compounds, such as:barbituric acid (1a), thiobarbituric acid (1b), 1,3-dimethyl barbituricacid (1c), phenol (1d) and resorcinol (1e) with diazotized o-nitroaniline(3), m-nitroaniline (4) and p-nitroaniline (5) catalyzed by p-toluenesulfonic acid(2) afford azo dyes by grinding in good yields. this new method totally avoidsthe use of inorganic acids, alkalies, toxic and/or expensive solvents indiazotization and diazo coupling reactions. prog. color colorants coat. 2(2009),61-70. © institute for color science and technology
