где R - водород, низший алкил, низша алкокси- или сульфогруппа, которые могут найти применение в качестве стабилизаторов полимеров, комплексообразователей или полупродуктов дл синтеза биологически активных соединений.where R is hydrogen, lower alkyl, lower alkoxy or sulfo, which can be used as stabilizers of polymers, complexing agents or intermediates for the synthesis of biologically active compounds.
В литературе описан способ получени одного из представителей класса сульфолантиолов , а именно бета-1,1-диоксотиолан-3-тиола , взаимодействием 2,5- или 2,3дигидротиофен-1 ,1-диоксидов с разбавленным водным раствором (15%-ным) гидросульфида натри при температуре 50- 60°С в течение 8 ч с последующей нейтрализацией сол ной кислотой, экстракцией хлороформом, удалением растворител и перегонкой в вакууме. Выход целевого, продукта 85% ..The literature describes a method for producing one of the representatives of the class of sulfolanthiols, namely beta-1,1-dioxothiolan-3-thiol, by reacting 2,5- or 2,3-dihydro-thiophene-1, 1-dioxides with a dilute aqueous solution (15%) sodium hydrosulfide at 50-60 ° C for 8 hours, followed by neutralization with hydrochloric acid, extraction with chloroform, removal of the solvent and distillation in vacuo. The yield of the target product is 85% ..
Однако, в литературе отсутствуют сведени о способе получени бета-1,1-диоксотиолантиолов указанной формулы, за исключеиием соединени этой формулы, где R - водород.However, there is no information in the literature about the method of obtaining beta-1,1-dioxothiolanthiols of the indicated formula, except for the compound of this formula, where R is hydrogen.
Целью изобретени вл етс разработка нового способа получени бета-1,1-диоксотиолантиолов указанной формулы, которыеThe aim of the invention is to develop a new method for producing beta-1,1-dioxothiolanthiols of the specified formula, which
за исключением одного соединени -1,1диоксотиолан-3-тиола , вл ютс новыми, неwith the exception of one compound -1,1 dioxothiolan-3-thiol, are new, not
