3-[2-(Triphenylphosphanylidene)acetyl]-2H-chromen-2-one

In the title compound, C(29)H(21)O(3)P, a coumarin-substitued ylid, the P atom is linked to three benzene rings and a planar coumarin moiety via a methylenecarbonyl group. The bond lengths in the P=C–C=O fragment clearly indicate a delocalized system involving the olefinic and carbonyl bonds. The m...
