摘要：

By reactions of the strongly electrophilic 2-methylthio-4,5-bis-(trifluoromethyl)-1,3-dithiol-2-ylium trifluoromethanesulfonate (6) with nucleophiles like secondary amines, phenoles and active methylene compounds the new 2-amino-1,3-dithiolium salts 11a-e and 1,3-dithiol-2-ylidene compounds 5-10, 12 were obtained. The 1,3-dithiolium salts 14 were prepared in two different ways. Reaction with PPh3 yields the phosphonium salt 16, from which the ethylidene compound 20 was obtained via the intermediate phosphorane 18. The crystal structures of 7, 16 and of the fulvalene 19 were determined.
