Wittig reaction of 2,2-disubsitituted cyclopentane-1,3-  dione

Abstract

During of studying the Wittig Reaction of 2,2-disubsitituted cyclopentane-1,3-dione, it was found that the product of the Wittig reaction was an alcohol rather than an olefin when sodium hydroxide was used as base, just like the product of Grignard Reaction. A pair of cis、 trans isomers was separated and the crystal structure of the cis isomer was determined by X-ray diffraction analysis. The probable mechanism for the novel product was proposed.

Key words: REACTION MECHANISM, PENTANEDIONE P, X-RAY DIFFRACTION ANALYSIS, WITTIG REACTION
