Abstract

5-Aza, 2, 3-benzo-5-aza-, 6-aza-, and 2, 3-benzo-6-aza-1, 4-dithiafulvalenes were synthesized and their spectroscopic properties are described. For example, the reaction of 2- methylthio-1, 3-dithiolylium iodide with pyrrole gave 2-(2-pyrrolyl)-1, 3-dithiolylium iodide in a 92% yield, which was treated with DBU, giving rise to 5-aza-1, 4-dithiafulvalene as thermally-stable orange crystals in an 82% yield. Several reactions found during the ...
