All compounds synthesized were identified by 1H NMR and elemental analysis. Some of them exhibited certain growth inhibition action to Phoma asparagi, Alternaria solani, Gibberella zeae, Physalospora piricola, Colletotrichum lagenarium as tested in vitro at dosage of 50 mg/L.展开更多
以二甲基亚砜为溶剂,1,4-对二氯苄和吡唑为反应物,微波辐射合成了1,4-二(吡唑基-1-亚甲基)苯。通过实验研究确定最佳合成条件为:微波输出功率为400W、间歇辐射时间为4min、n(吡唑)∶n(对二氯苄)=2.2∶1。最佳条件下产率可达79.6%。经元...以二甲基亚砜为溶剂,1,4-对二氯苄和吡唑为反应物,微波辐射合成了1,4-二(吡唑基-1-亚甲基)苯。通过实验研究确定最佳合成条件为:微波输出功率为400W、间歇辐射时间为4min、n(吡唑)∶n(对二氯苄)=2.2∶1。最佳条件下产率可达79.6%。经元素分析及IR、1 H NMR表征,确认了合成产物结构。展开更多
