Abstract
The 2-phospha-1,3-butadiene derivatives <bold>3</bold> are readily accessible by reduction of <bold>2</bold> with Mg. Sequential one-electron oxidation of <bold>3</bold> with GaCl<sub>3</sub> leads to the formation of radical cations <bold>4</bold> and dications <bold>5</bold> as crystalline solids.
