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

摘要

Syntheses of isothioureas3a–3eand 1-aza-butadiene-derivatives4a–4eare described, starting from bis-alkylmercaptomethyleneimides1a-1eand 1,1-bis-(dimethylamino)-ethylene (2). Reactions of isonitriledichlorides5a–5cwith alkylmercaptanes and aromatic amines in the presence ofn-Butyl-lithium yield the isothio-ureas6a–6c;7with2gives — in the presence of triethylamine—the 1-azabutadienederivative8.
