Thiophosgene and Related Compounds

Although carbon disulfide does not normally react with 1,3-dienes, other thiocarbonyl compounds in this oxidation state are generally reactive dienophiles. Thiophosgene has been added to several different [Pg.132]

Under slightly different conditions, the thiolactone can be obtained. [Pg.134]

Alternative precursors for the synthesis of NHCs are thiourea derivatives of type 14. Kuhn and Kratz first reported a facile method for the synthesis of symmetrically substituted imidazol-2-thiones by the reaction of 3-hydroxy-2-butanone with suitable thiourea derivatives (Scheme 1.8a). Related saturated imidazolin-2-thiones 15 or benzimidazol-2-thiones 16 were obtained by reaction of aliphatic or aromatic 1,2-diamino compounds with thiophosgene (Scheme 1.8b). Unsymmetrically substituted imidazolin-2-thiones 17 were obtained by the reaction of lithium-A-lithiomethyldithiocarbamates with aldimines and ketimines, respectively (Scheme 1.8c). ... [Pg.9]
