Изобретение относитс к новому способу получени арилэтиниларилселенидов формулыThis invention relates to a new process for the preparation of aryl ethynylaryl selenides of the formula
R-Se-C C-R,ТR-Se-C C-R, T
где R - незамещенный или замещенный галогеном, низшим алкилом или низшей алкоксигруппой фенил, которые могут найти применение в качестве полупродуктов в различных органических синтезах .where R is phenyl unsubstituted or substituted by halogen, lower alkyl, or lower alkoxy, which can be used as intermediates in various organic syntheses.
Известен способ получени зтинилселенидов формулы I, где R - арил, заключающийс в том, что соответствующий селенол т натри подвергают взаимодействию с соответствующим галоид этиниларилом в дикетилформамиде. Выход целевых продуктов 40-72% f1.A known method for producing zelenilenides of the formula I, where R is aryl, is that the corresponding sodium selenolate is reacted with the corresponding ethylenyl aryl halide in di-methylformamide. The yield of the target products 40-72% f1.
Однако к недостаткам известного способа относ тс необходимость предварительного синтеза галоидэтиниларилов , веществ труднодоступных, легко осмол ющихс и взрывоопасных, что в целом усложн ет процесс, относительно невысокий выход целевыхHowever, the disadvantages of the known method include the need to pre-synthesize haloethylenilaryl, substances that are difficult of access, easily osmolyable and explosive, which generally complicates the process, the relatively low yield of the target
продуктов и, кроме того, по известному способу получают ограниченное количество целевых продуктов.products and, in addition, by a known method receive a limited number of target products.
Целью изобретени вл етс упрощение процесса, повьш1ение выхода и расширение ассортимента целевых продуктов.The aim of the invention is to simplify the process, increase the yield and expand the range of target products.
Поставленна цель достигаетс способом получени соединений формулы i, заключающимс в том, что The goal is achieved by the method of obtaining compounds of the formula i, which consists in the fact that

Выход целевых продуктов 64-84%.The yield of the target products 64-84%.
Способ провод т следующим образом .The method is carried out as follows.
На сС-брометирил-(арил)-селенид On cC-bromethyl- (aryl) -selenide
20 формулы И, полученный взаимодействием арилселенилбромида арилацетиленом в лед ной уксусной кислоте (2550 ), невыдел его в чистом виде,20 of formula I, obtained by the reaction of arylselenyl bromide by arylacetylene in glacial acetic acid (2550), was not isolated in pure form,
