Julolidine synthesis

For example, the julolidine-substituted dithiolene (9) can be obtained18 in low yield by standard procedures the synthesis of the red, crystalline dithione and its conversion to (9) under reducing conditions proceeds in high yield.24 Dithiones are only stable if they are substituted by strongly electron-donating or -withdrawing substituents, and their use is limited to these cases.
