摘要：

In the title ylide, C31H28ClO2P [ common name alpha- acetyl-alpha-p-chlobenzoylmethylenetri( p-tolyl) phosphorane], the dihedral angle between the 4-chlorophenyl ring and that of the ylide moiety is 66.15 (10) (degrees). The geometry around the P atom is slightly distorted tetrahedral [angle range = 105.22 (8)115.52 (9)(degrees) ] and the carbonyl O atoms are syn-oriented with respect to the P atom. The ylide group is close to planar [maximum deviation from the least-squares= 0.006 (2) A(degrees) and the P-C, C-C and C=O bond lengths are consistent with electron delocalization involving the O atoms.
