  THE BEHAVIOR OFN-PHENYLIMINOPHOSPHORANE TOWARDSo- ANDp-QUINONES. NEW SYNTHESIS OF DIOXAZOLE AND OXADIAZOLE DERIVATIVES

  摘要：

  N-Phenyliminophosphorane (1) reacts with 9,10-phenanthrenequinone (2a) to give the new products 2-phenylphenanthro[9,10-d][1,3,2]dioxazole (4a) and (10Z)-10-(phenylimino)-9(10H) phenanthrenone (4b). The reaction of I with 1,2-naphthoquinone (2b) afforded both the dioxazole derivative 5a and the known 2-anilino-naphthoquinone-1,4-anil (5b). On the other hand, 2,6-di-tert-butyl-2,3-diphenyl-2,3-dihydro-1,2,3-benzoxadiazole (6) was obtained from the reaction of (2c) with phosphinimine (1). Application of reagent 1 on 2d and 2e renders (6E)-2,3,4,5-tetrahalogeno-6-(phenylimino)-2,4-cyclohexadien-1-one 7a and 7b, respectively. Moreover, p-quinones (3a-3c) react with phosphinimine (1) to yield products 8, 9 and 10, respectively. Mechanisms accounting for the formation of the new products are discussed and the probable structures of the products are presented based on analytical and spectroscopic data.

• Quinone imine dye formation via photocycloaddition between isocyanates and chloranil

  日期：2004.6

  Photochemical [2+2]cycloaddition between electron-donating aryl isocyanates and chloranil was observed in acetonitrile or benzene, and the following elimination of carbon dioxide resulted in the formation of the corresponding quinone imine dyes. This new route for synthesis of quinone imine was investigated by product analyses, laser flash photolyses, and molecular orbital calculation.
