4-Bromobenzoylmethylene–triphenylphosphorane ylide

Abstract

In the mol­ecule of the title compound, (4-bromo­benzo­yl)(triphenyl­phospho­nio)methanide, C26H20BrOP, the geometry around the P atom is nearly tetra­hedral and the O atom is oriented cis to the P atom. The bromo­phenyl ring of the benzoyl group is twisted with respect to the plane of the carbonyl group through an angle of 3.83 (3)°.
