Synthesis, structure and reactivity of cyclopropenyl-1-ylidene stabilized S(II), Se(II) and Te(II) mono- and dications

The syntheses and structural characterization of carbene-stabilized chalcogen centred mono- and dications employing a reverse electron demand onio-substitutent transfer strategy are reported. The electronic structures of these compounds were determined by density functional calculations and their reactivity towards Pd(0) centres was evaluated.
