Abstract: | 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.Herrn KollegenHans Musso, Karlsruhe, mit den besten Wünschen zum 60. Geburtstag, in dankbarer Erinnerung an die gemeinsame Karlsruher Zeit, gewidmet. |
