reacted readily with trifluoroaceticanhydride (TFAA) to give the trifluoroacetylphosphines 7 and 8. (1-Ad)2P(:O)H (6) could not be converted into the corresponding trifluoroacetylphosphine oxide 10 by treatment with TFAA. Compound 10 was observed by 19F and 31P NMR spectroscopy in the reaction of (1-Ad)2PC(:O)CF3(7) with (H2N)2C(:O) · H2O2. Two pathways were observed for the reaction of 1 with excess
