  摘要：

  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.

  Abstract The reaction of hexafluoroacetone (HFA) with the benzoxazaphosphorinone 1 leads to the λ5-oxazaphosphepinone 2. In several cases unusual products, 3, 8 - 14, 16, and 17, were isolated in the reactions of 1, 4 - 7, and 15 with HFA, tetrachloroorthobenzoquinone (TOB) and perfluorinated 1,2-diketones. X-Ray crystal structure analyses were carried out for the derivatives 2, 3, and 8 - 10.
