In the previous paper, we reported the formation of bis(O,O-diethyldithiophosphate) disulfide as an intermmediate product in the course of chlorination of O,O-diethyldithiophos phoric acid. During the past decade, much effort has been directed towards the synthesis of mixed phosphoric esters and esters of phosphoric anhydrides, some of them being found as powerful insecticides. The disulfide with the general, known as "phos phatogen," has not been closely investigated, and apart from isolated cxamples, little about this class of compounds has been recorded in the li'erature. Considering their possible insecticidal and fungicidal activities, we prepared a series of the disulfides, aliphatic as well as aromaic, and examined some of their chemical properties.In connection with the investigation stated above, we needed various O,O-dialkyldithiophos phoric acids as intermmediates. The reaction bstween monohydroxy alcohols, polyhydroxy alcohols and different types of phenols with phosphorus pentasulfide were studied. Methyl, ethyl, i-propyl, n-butyl, i-butyl, i-amyl i-amyl and cyclohexyl alcohols reaced with phosphorus pentasulfide smoothly to give O,O-dialkyldithiophosphoric acids in 80-90% yield. The reaction product of polyhydroxy alcohols, namely, ethylene glycol, trimethylene glycol, or glycorol with phosphorus pentasulfide was not homogeneous; we failed to isolate from it the expected product. Although pbenol and β-naphthol reacted with phosphorus pentasulfide equally smoothly, no expected dithiophosphoric acids were obtained from chlorophenols and nitrophenols.Pure sodium salts of the O,O-dialkyldithiophosphoric acids were oxidized by calculated amount of bromine in cold aqueous solution to give the disulfides in 58-85% yield. Eight different disulfides, were propared, where R represents methyl, ethyl, i-propyl, n-butyl, i-butyl, n-amyl, i-amyl, cyclohexyl or phenyl radical. Among these substances only the last one decomposed spontaneously in anhyhrous state within a few days, while the other members were quite stable and unchanged after four months.The disulfides exhibited typical radical or polar cleavage reactions of the unit, since they dissolved in cold aqueous sodium sulfide to form sodium salts of the ditbiophosphoric acid with separation of free sulfur. In alcoholic silver nitrate, they separeted in the form of silver salts of the corresponding dithiophosphoric acids according to the following equation:With alcoholic mercuric chloride, the formation of a double salt instead of the cleavage of -S-S-bond was observed. A series of the double salts with the general formula were prepared, where R represents methyl, ethyl, i-propyi, n-butyl, i-butyl, i-amyl, cyclohexyl or phenyl radical.

本實驗研究了各類醇及酚与五硫化二磷的作用,各種一元醇,苯酚与β-萘酚与五硫化二磷生成相當的二硫代磷酸O,O-二烴基酯,但多元醇,氯代苯酚,硝基苯酚与五硫化二磷作用後,均未得預期的產物。本實驗合成了八種二硫代磷酸O,O-二烴基酯的汞鹽,九種雙(硫代磷酸O,O-二烴基酯)二硫物及八種二硫物的氯化汞複鹽。二硫物是一類比較活潑的化合物,其-S-S-鍵易被離子化藥劑所離解,同時呈一定的氧化性能。二硫物有失去一個硫原子的傾向,硫原子成為游離狀態析出或与金属成硫化物。

This is a literature review on the new and important developments as to the theoriesand their applications concerning the biological and chemical control of insects of medicalimportance. Under the heading of biological control, Knipling's theory of the use of insects fortheir own destruction together with the recent progress in sterility by means of atomicradiation, experimental studies on chemical sterilants, and the concept of geneticsterility by hybridization is treated and commented at some length. In the field of chemical control, the author calls attention to the residual fumiganttechnic, the semi-permanent insecticidal resins and the animal systemic insecticides as wellas their significance in insect control at present br in future. In addition, studies on insectattractants and their potential use in insect control are discussed.

本文系一文献综述,重点介绍近来防制医学昆虫研究方面的重大发展,对今后防制研究的方向方法,具有一定的战略战术意义。 首先介绍了新的生物学防制理论和方法。应用射线不育性方法消灭贪食美蝇已在中、北美取得成功,而且创造了区域性灭种的范例。它进一步孕育了昆虫自灭(绝嗣)方法的理论。化学不育性方法正在研究探索中,实验室试验已初步证明某些药物可使蚊蝇不育,乃一新生萌芽。遗传不育性方法尚在假设阶段,能否成功,还待试验证明。 其次在化学防制方面,现已出现几种新的途径。滞留熏蒸杀虫剂可在有人而通风的房舍中使用,其蒸气能熏杀昆虫,但对人比较安全,现已接近应用阶段。家畜动物通过内服药物等途径以毒杀其体内外的寄生或吸血昆虫已有了开端。与上述两法有关的有机磷杀虫剂,其慢性中毒问题。尚须进一步研究。杀虫树脂是一新的剂型,其杀虫毒效远比一般滞留喷洒为持久,且可在擦洗频繁的场所使用,现已推广应用。在诱虫剂方面亦有一定的进展。看来诱虫剂加杀虫剂和化学不育剂可能成为未来防制害虫的有效方式。
