Synthesen,spektroskopische Eigenschaften von Alkylmercaptoalkylaminomethylensulfonamiden und chemisches Reaktionsverhalten von 1,1-Bis-(dimethylamino)-ethylen

Syntheses of isothioureas3a–3e and 1-aza-butadiene-derivatives4a–4e are described, starting from bis-alkylmercaptomethyleneimides1a-1e and 1,1-bis-(dimethylamino)-ethylene (2). Reactions of isonitriledichlorides5a–5c with alkylmercaptanes and aromatic amines in the presence ofn-Butyl-lithium yield the isothio-ureas6a–6c;7 with2 gives — in the presence of triethylamine—the 1-azabutadienederivative8. The sulfoneamides9a–9e yield with2 the amidines10a–10e.11 resp.13 react with2 to the compounds12 and14 in relatively good yields.
