Abstract
Изобретение относитс к химии мышь корганических соединений, в частности к способу получени тетраалкил(арил)диареинов общей ф-лы [(R)2-AS]2, где R - низший алкил или фенил, которые могут найти применение дл получени металлического мышь ка полупроводниковой чистоты, диалкиларсиновых кислот или их солей арсони . Цель изобретени - упрощение процесса и увеличение выхода целевых продуктов. Процесс ведут реакцией соответствующего реактива Гринь ра с реальгаром ф-лы AS2S2 при охлаждении в абсолютном эфире в течение 0,5 ч, а затем 5 ч при кипении растворител . Значени RThe invention relates to the chemistry of mice with organic compounds, in particular to a method for producing tetraalkyl (aryl) diarrheas of the total fi [[R) 2 -AS] 2 , where R is lower alkyl or phenyl, which can be used to produce a semiconductor metal mouse purity, dialkylamino acids or their salts arsoni. The purpose of the invention is to simplify the process and increase the yield of the target products. The process is carried out by the reaction of the corresponding Grignard reagent with realgar f-ly AS 2 S 2 while cooling in absolute ether for 0.5 h, and then 5 h at the boiling point of the solvent.

При меры 2-5. Осуществл ют аналогично примеру 1 с той разницей, что после отгонки эфира остатки фракционируют под вакуумом в токе углекислого газа. Загрузка исходных веществ и некоторые физико-химические характеристики синтезированных соединений приведены в табл,1.Examples 2-5. Carried out as in Example 1 with the difference that after the distillation of the ether, the residues are fractionated under vacuum in a stream of carbon dioxide. The loading of the initial substances and some physicochemical characteristics of the synthesized compounds are given in Table 1.
В табл.2 приведены данные по содержанию примесных металлов в исходном реальгаре и в металлическом мышь ке, полученном из диалкилдиар- .ллов.Table 2 shows the data on the content of impurity metals in the initial realgar and in the metal mouse obtained from dialkyl diaryl lolls.
Таким образом, предложенный способ получени диалкил(арил)-диарси- лов позвол ет упростить процесс ихThus, the proposed method for the preparation of dialkyl (aryl) -darylsyl allows to simplify their process.

They can be used to obtain resins, lacquers, liquids, rubbers with enhanced thermal-oxidative stability. A method is known for preparing this compound by reacting organochlorosilanes with o-chlorophenyls at 500-700 ° C. The advantages of such a method are to carry out the synthesis at high temperatures (700 ° C), a significant percentage of bottom fraction, and the use of trichlorosilane (the ratio between o-chloridiphenyl and trichlorosilane is at least 1: 2). | |
