Description

Изобретение относитс  к области получени  iHOBoro класса кремнийорганических соедашешй-ацилнзотиоцианатов общей формулыThe invention relates to the field of obtaining iHOBoro class of organosilicon compounds-acyl nisothiocyanates of the general formula

Кремнийсодержащие ащшизогиоцианаты могут представл ть большой интерес дл  получени  биологэгчески шстивных веществ, в качестве полупродуктов дл  синтеза других классов кремнийорганических соединений (например, ацилтиомочевин, ацилтиоуретанов ), а также как моно|теры дл  модификации .|уже известных органических и кремнийорганических полимерных материалов. В литературе отсутствуют данные о таких соединени х.Silicon-containing azysocyanates may be of great interest for the production of biologically active substances, as intermediates for the synthesis of other classes of organosilicon compounds (for example, acylthioureas, acylthiourethanes), and also as monomers for modification of already known organic and organosilicon polymeric materials. There is no data in the literature about such compounds.

Предлагаемый способ заключаетс  во взаимодействии галоидангидридов силикарбоновых кислот общей формулы:The proposed method consists in the interaction of siliconic carboxylic acid halides of the general formula:

Взаимодействие осуществл ют в отсутствие растворителей нагреванием кремнийорганического «хлорашидрида с| эквимол рным количеством или небольшим избытком изотиоцианатосилана п ри неп рерьюной отгонке выдел ющегос  галогенсилака. Дл  .предотвращени  ynocz вместе с галогенсиланом исходного изотиоцианатосилана в тех случа х, когда эти соединени  имеют близкие температуры кипени , реакцию удобнее всего проводить в кубе ректификационной колонки, отбира  галогенсилан по мере его образовани . Реакци  с достаточно высокой скоростью протекает при 100-150°С и заканчиваетс  в этих услови х за врем  от нескольких дес тков минут до .нескольких часов. Более высока  температура реакThe reaction is carried out in the absence of solvents by heating the organosilicon "chlorohydride with | an equimolar amount or a slight excess of isothiocyanatosilane in the case of non-recurrent distillation of the liberated halogenilac. To prevent ynocz with the halogen-silane of the starting isothiocyanatosilane in cases where these compounds have similar boiling points, it is most convenient to carry out the reaction in the bottom of a distillation column, selecting the halogen-silane as it is formed. The reaction proceeds at a sufficiently high rate at 100-150 ° C and ends under these conditions from a few tens of minutes to several hours. Higher temperature
