- 摘要：
- (I) is prepd. by reacting 4,5,6-trichloropyrimidine at 150-250 degrees C with excess gaseous Cl2 under u.v. irradiation. (I) has fungicidal activity partic. against Fusicladium dendriticum and can also be used in prodn. of pigment dyes e.g. anthraquinone dyes; on heating 1 mole (I) with 2.5 moles 1-aminoanthraquinone in nitrobenzene at 200 degrees C in the presence of a trace of anhydrous FeCl3 a yellow pigment is formed.
