The preparation of 2-phenyl-4-dimethylamino-l-aza-, 1-oxa-, 1-thia-, l-selena-3-azabuta-l,3-dienes as well as their 4-methyl derivatives is described following a new heteroatom interchange reaction process. Heteronucleophilic attack at one particular reactive site of bis-electrophilic amidinium salts is the key feature of the process. In addition, we also disclose that the substituted l-oxa-3-aza- and l,3-diazabuta-l,3-dienes can be obtained by a reactional transformation cascade initiated by either silver acetate addition or tosyl azide [3+2] cycloaddition onto the CS or CSe double bonds of the 1-thia- and l-selena-3-azabuta-l,3-diene analogues.
