Abstract

Ionic compounds containing phosphorus-based cations represent an important new direction in the fundamental chemistry of nonmetal elements.In this work, we explored the reactivity of phosphino-phosphonium cations with sulfur and selenium, with a view towards new synthetic methods for phosphorus-chalcogen cations. We present several new cations which have been identified by P-31 NMR spectroscopy and single crystal x-ray diffraction, that are analogous to the recently reported chalcogenides of phosphanylboranes. We also present new diphosphonium-diselenide cations which have been formed through a unique redox equilibrium of triphenylantimony(V) bistriflate and trialkylphosphineselenides on one side and the diphosphonium diselenide cations and triphenylantimony(III) on the other side.
