二硫代磷酸 O,O-二烃基酯或其汞盐与二乙基汞很顺利地进行下列反应:(?) (?)这两个反应可利用来制备各种二硫代磷酸 O,O-二烃基酯乙基汞盐。这里制备了九种同系物。在报告Ⅱ中所制备的二硫代磷酸 O,O-二β-萘基酯,表现有2,4-D 类型的植物刺激作用,双-(O,O-二烃基硫磷酸酯)二硫物的杀虫(粘虫三龄幼虫)及杀菌(Alternariatenius)效能均甚微弱。但是本报告中所制备的二硫代磷酸 O,O-二烃基酯乙基汞盐同时具有杀虫(粘虫的三龄幼虫)及杀菌(Alternaria tenius)的效能。其中有六种,如以含汞量计,它们的杀菌效能较氯化乙基汞为强。
The O, O-dihydrogen phosphorodithioate or its mercury salt and diethylmercury smoothly proceed as follows: (?) (?) Both reactions can be used to prepare various phosphorodithioates O, O Dihydrocarbyl ethylmercuric salts. Nine homologs were prepared here. The O, O-di-β-naphthyl phosphorodithioates prepared in Report Ⅱ exhibited plant irritation with the 2,4-D type, bis- (O, O- dihydrocarbyl thiophosphate) disulfide Insecticides (3rd instar larvae of armyworms) and Alternariatenius are weak. However, the O, O-dihydrocarbyl ethyl mercury dithiophosphorothionate prepared in this report possesses both the efficacy of insecticidal (third-instar larvae of armyworm and Alternaria tenius). There are six of them. For example, in terms of mercury content, their germicidal efficacy is stronger than that of ethylmercury chloride.
