WebThe phospholide moiety of a monophosphaferrocene was acetylated by treatment with acetic anhydride in the presence of trifluoromethylsulfonic acid 〈87ICA93〉. Again the acetylated phosphole was not released from the complex. Benzoyl chloride also was used to benzoylate the phospholide moiety of (286) (Equations (64a) and (64b)).
