readily oxidized to (C6H5)2P(O)C(OH)(CF3)2 and, in the presence of base catalyst, undergoes rearrangement to the isomeric (C6H5)2P(O)OCH(CF3)2. Reaction of hexafluoroacetone with diphenylarsine gives (C6H5)2AsC(OH)(CF3)2 while reaction with diphenyl phosphonate gives (C6H5O)2P(O)C(OH)(CF3)2 which rearranges to (C6H5O)2P(O)OCH(CF3)2.

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
