Project description:In the title ylide, C(31)H(28)ClO(2)P [common name ?-acetyl-?-p-chloro-benzoyl-methyl-enetri(p-tol-yl)phospho-rane], the dihedral angle between the 4-chloro-phenyl ring and that of the ylide moiety is 66.15?(10)°. The geometry around the P atom is slightly distorted tetra-hedral [angle range = 105.22?(8)-115.52?(9)°] 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 plane = 0.006?(2)?Å] and the P-C, C-C and C=O bond lengths are consistent with electron delocalization involving the O atoms.

Crystal structure of 2,2-di-chloro-1-(piperidin-1-yl)butane-1,3-dione.

Project description:In the title compound, C9H13Cl2NO2, the piperidine ring shows a chair conformation and the O-C-C-O torsion angle between the carbonyl groups is 183.6 (4)°.
