Abstract

Inventia se refera la derivati de 1,3-ditiol-2-tione cu formula generala I: (vezi formula) în care R reprezinta un atom de hidrogen sau un radical metil sau etil, produse cristaline, de culoare galbena cu puncte de topire în intervalul 200...250 degree C, care se obtin plecând de la perclorati de 2-dialchilamino-1,3-ditioliu cu formula generala II: (vezi formula) în care R are semnificatiile de mai sus, R1 si R2 aceiasi sau diferiti reprezinta fiecare un radical alchil inferior sau împreuna radicalul (CH2)2-O-(CH2)2 care se trateaza cu sulfura de sodiu în mediu de alcanol inferior la o temperatura cuprinsa între 20 si 25 degree C, urmata de acidulare cu acid clorhidric.The invention relates to 1,3-dithiol-2-thione derivatives of the general formula I wherein R represents a hydrogen atom or a methyl or ethyl radical, a yellow crystalline product of melting points in the range of 200-250 ° C, obtained from the 2-dialkylamino-1,3-dithiol perchlorates of general formula II wherein R is as defined above, R 1 and R 2 are the same or different each represents a lower alkyl radical or together the radical (CH 2) 2 -O- (CH 2) 2 which is treated with sodium sulphide in a lower alkanol medium at a temperature of between 20 and 25 ° C, followed by acidification with hydrochloric acid.
