3-Chloro-1,1,1-trifluoro-3-(triphenylphosphoranylidene)propan-2-one

Abstract

Key indicators: single-crystal X-ray study; T = 273 K; mean (C-C) = 0.003 Å; R factor = 0.035; wR factor = 0.090; data-to-parameter ratio = 13.8.The title compound, C 21 H 15 ClF 3 OP, was obtained by a convenient and efficient one-pot synthesis. The length of the C C bond indicates a large enolic contribution to the structure. Intra-and intermolecular C-HÁ Á ÁO hydrogen bonds are present in the crystal structure.
