  Fluoroaliphatic hydroxyketoradicals prepared by photochemical reduction of the corresponding α-diketones and (i-C3F7)2C⋅C(O)CF3 react with hydrogen abstraction (according to ESR data). The hydroxyketoradicals are shown to dimerize reversibly, and the dimerization rate decreases in the presence of polyfluorinated alcohols due to the formation of radical–alcohol complexes.

  anions formed by reduction of α-diketones RC(O)C(O)CF3 (R=(CF3)2CF, C6F5, (CF3)3C) with metals (Li, Na, K, Mg, Cd, Zn, Hg, In, and TI) in THF were studied. For R=(CF3)2CF and C6F5, the radical anions are formed ascis-isomers, whereas for R=(CF3)3C,trans-isomers are obtained. Line broadening due to solvation and desolvation of the cation is observed in the latter case. The reduction of α-diketone (CF3)2CFC(O)C(O)CF3

  two isomers 12a and 12b was observed. Reaction of a mixture of 12a and 12b with water led to 2-hydroxy-2-oxo-triazaphosphorinan-4,6-dione (15) and two further perfluorinated products 13 and 14. Dimethylphosphine oxide (3) reacted with perfluoro-isobutylmethyl ketone (4) to give the perfluoroalkyl-substituted α-hydroxyphosphine oxide 16. In contrast to 7-12, compound 16 was shown to contain the P-C-OH

  New Phospholene and Phosphepine Derivatives from λ3‐Phosphorus Compounds and Hexafluoroacetone or Perfluorinated α‐DiketonesThe reaction of the bis(2‐chloroethyl)amino‐substituted benzoxazaphosphorinone 1 with hexafluoroacetone (HFA) proceeds with insertion of the carbonyl group of HFA into the heterocycle of 1 to form the oxazaphosphepinedione 2. Triethyl phosphite (3) and triphenyl phosphite (4) react with the perfluorinated diketones 5 and 6 with formation of the pentaoxyphosphoranes 7–10 containing a dioxaphospholene ring system. The reaction of the (2‐chloroethyl)amino‐ and bis(2‐chloroethyl)amino‐substituted 1,3,5,2‐triazaphosphorinanediones 11–14 with the perfluorinated diketone C2F5C(:O)C(:O)CF3 (15) furnishes spirophosphorane derivatives with the dioxaphospholene ring system, 16 and 17, in two cases only. Compound 1 and 2‐[bis(2‐chloroethyl)‐amino]‐4H‐1,3,2‐benzodioxaphosphorin‐4‐one (18) react with the perfluorinated α‐diketones 5 and 6 with insertion of the diketones into the heterocycle of 1 and 18 with formation of compounds 19–22 containing dioxa‐ and oxazaphosphepinone ring systems. The expected oxidative addition of the diketones to λ3P with formation of spirophosphoranes was not observed. Compounds 19–22 were obtained as mixtures of isomers (19a/b–22a/b). Single crystal X‐ray structure analyses were conducted on 2 and 9. The seven‐membered ring of 2 displays a “tub” conformation, with the O and benzo C atoms lying out of the plane of the other four atoms. The two independent molecules of 9 are similar, but differ in the degree of distortion from trigonal‐bipyramidal geometry of phosphorus.
