It has been found that the reaction of the 1,2-ethanediylbis(trithiocarbonic acid) dianion with haloacetic esters, chloromethyl ethers, and chlororhethyl sulfides in tetrahydrofuran proceeds smoothly to afford 1,2-ethanediylbis(alkoxycarbonylmethyl trithiocarbonates), 1,2-ethanediylbis(alkoxymethyl trithiocarbonates) and bis(alkylthiomethyl) trithiocarbonates plus ethylene trithiocarbonate respectively
und sek. Aminen. Während die Umsetzung mit 2‐Chlorethylbenzylether mißglückte, waren die Alkylthioethylamide 12 und 13 und die Dialkylaminoethyl‐Verbindungen 15–19 darzustellen. Mit anderen Trialkylsulfonyldiamiden wurden 2 und 8, mit Trimethylsulfonyldiamid sowie mit 1‐Ethyl‐3,3‐dimethylsulfonyldiamid und 3‐Chlorpropyldiethylamin 20 und 21 gewonnen.

(Alkoxymethyl)dodecyldimethylammonium, (cycloalkoxymethyl)dodecyidimethylammonium, (alkylthiomethyl)dodecyldimethylammonium, (alkoxymethyl)dimethyloctylammonium, (cycloalkoxymethyl)dimethyloctylammonium and (alkylthiomethyl)dimethyloctylammonium chlorides were prepared in high yield. All the chlorides studied showed antimicrobial activity. The relationship between the chemical structure and antimicrobial activity was analyzed using the rough sets method.
3-oxathiolane was deprotonated at the 4-position, followed by the cycloelimination of the resultant anion, leading to ethyl formate and the ethenethiolate anion. The anion was trapped by several chloromethyl alkyl ethers and sulfides to afford alkoxy(vinylthio)methanes and alkylthio(vinylthio)methanes respectively.

compound in poor yields along with ten other compounds. Under similar conditions, 2-lithio-1,3-dithiane on treatment with 2 and bis-(trifluoromethyl)disulfide (4) gave 8.0% and 10.0% yields of 1, respectively. In connection with this study, (cholromethyl) propyl sulfide and bis-(propylthio)methane were synthesized. The reaction of the latter with 3 was also investigated. The characterization of the primary
