title: Cycloaddition of phosphanylidene-sigma4-phosphoranes ArP=PMe3 and quinones to yield 1,3,2-dioxophospholanes.
abstract: The reaction of phosphanylidene-[sigma](4)-phosphoranes ArP=PMe(3)(Ar = 2,6-Mes(2)C(6)H(3) or 2,4,6-t-Bu(3)C(6)H(2)) with select ortho-quinones yields 1,3,2-dioxophospholanes, one of which shows interesting [small pi]-stacking of the aromatic groups in the solid state.
