Pyrophosphoric acid → HCID 178519397, compound

Participants

Reaction Steps

5.30 of p-chlorobenzoic acid, 1.0 ml of triethylamine, and 2 ml of phosphorus oxychloride were added and stirred at 0° C. for 30 minutes with 40 ml of methylene chloride, and 60 ml of pyrophosphoric acid and 6.0 g of ferrocene were added. The resulting mixture was heat-refluxed, then poured into water, and made to be basic with sodium hydroxide, subjected to extraction with methylene chloride, and dried. Subsequently, the unreacted ferrocene was removed with column chromatography, to obtain 6.16 g of p-chlorophenylferrocenyl ketone represented by the formula (E), in a yield of 61.0%. The proton nuclear magnetic resonance (1H--NMR) spectrum of the product is shown in FIG. 5. The result showed that the resulting product was the desired compound (p-chlorophenylferrocenyl ketone). ##STR12##
