Reaction Steps

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).
