| Summary: | Abstract Cyclopropylacetylene and N,N,N′,N′,N′′,N′′- hexamethylguanidinium chloride ( 1a ) react to give the orthoamide derivative 8c , in the presence of sodium hydride. 8c is transformed by elemental iodine to the vinylogous guanidinium salt 6f . Anion metathesis with the salts 5a , 5e , 6g delivers vinylogous guanidinium salts 5e – 5i , 12a with counter ions derived from carbon acids (tricyanomethane, 1,1,3,3-tetracyano-propene). Phenylogous amidinium salts 15 guanidinium salts 19 , 21 and the phenylogous orthoamide derivatives of formic acid 18 and carbonic acid 33 have been prepared. |
