• 精喹禾灵是在合成禾草克的过程中去除了非活性的光学异构体后的改良制品。其作用机制和杀草谱与禾草克相似，通过杂草茎叶吸收，在植物体内向上和向下双向传导，积累在顶端及居间分生，抑制细胞脂肪酸合成，使杂草坏死。精喹禾灵是一种高度选择性的新型旱田茎叶处理剂，在禾本科杂草和双子叶作物间有高度的选择性，对阔叶作物田的禾本科杂草有很好的防效。精喹禾灵作用速度更快，药效更加稳定，不易受雨水气温及湿度等环境条件的影响。

2）上述产物经碱性水溶液处理，生成相应的喹喔啉酮氮氧化物。以甲苯-水为溶剂，在氢氧化钠(或氢氧化钾)存在下，于60～70℃反应1h制得。

3）氮氧化物在碱水溶液中，于室温下，与一定量的30%硼氢化钠反应，得6-氯-2(1H)-喹喔啉酮。

4）6-氯-2(1H)-喹喔啉酮在DMF溶液中与氯化亚砜作用，得2，6-二氯喹喔啉。

5）喹禾灵的制备 在氮气保护下、DMF中，2，6-二氯喹喔啉与对苯二酚缩合(碱性条件)可得到4-(6-氯-2-喹喔啉氧基)酚，且收率较高。

6）然后在乙腈溶液中，以碳酸钾为缚酸剂，4-(6-氯-2-喹喔啉氧基)酚与α-卤代丙酸乙酯缩合，合成喹禾灵。
