실험 절차

Furthermore, it is known from Liebig's Annalen der Chemie, Volume 626, pages 26 to 34 (1959) to react benzaldehyde with triphenylphosphine dichloride to give benzal chloride, but the yield is only 59%. When cyclohexanone is reacted with triphenylphosphine dichloride in the presence of an equimolar amount of triethylamine it is not the corresponding geminal dihalide which is obtained but 1-chlorocyclohex-1-ene in 45% yield (loc. cit., page 33).
