Formation of <i>cyclo</i>‐E₄²⁻ Units (E₄=P₄, As₄, AsP₃) by a Complex with a CrCr Quintuple Bond

Abstract

White phosphorus, yellow arsenic, and AsP3 have been successfully activated by a complex with a CrCr quintuple bond in one step leading to the formation of rare terminally bound cyclo-P42−, cyclo-As42−, and cyclo-AsP3 units. The subsequent reaction with an excess of [W(CO)5(thf)] leads to the coordination of one {W(CO)5} fragment in the thermodynamically most stable form according to DFT calculations.
