The reaction of dimethyldioxirane with chrysene: Formation of a trioxide

Oxidation of chrysene with dimethyldioxirane gives a number of products including the interesting trioxide, chrysene-5,6:4b, 10b:11,12-trioxide, 3. The x-ray crystallographic structure of 3 indicates that it is a non-planar system.

Arene Imine Derivatives of Chrysene and of Benzochrysene: 1a,11c-Dihydrochrysenoazirine and 1a,13c-Dihydrobenzochrysenoazirine

The syntheses of the K-imines (which are also benzo-bay-region derivatives) of chrysene (1) and benzochrysene (2) are described.The preparation of 1a,11c-dihydrochrysenoazirine (5) was accomplished by treatment of 1a,11c-dihydrochrysenooxirene (4) with sodium azide, and the mixture of trans-azido-alcohols 6 and 7, so formed, was either cyclized with triethyl phosphite, or converted into E-6-azido-5-chloro-5,6-dihydrochrysene (8) followed by lithium aluminium hydride reduction.The synthesis of 1a,13c-dihydrobenzochrysenoazirine (12) included the transformation of the corresponding oxide 11 into a mixture of E-9-azido-9,10-dihydrobenzochrysen-10-ol (13) and E-10-azido-9,10-dihydrobenzochrysen-9-ol (14), and reaction with tri-n-butylphosphine to give a mixture of Staudinger adducts 15 and 16 that underwent thermal decomposition into 12 upon heating in boiling dichloromethane.
