| Abstract: | 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. |
