  Tetracyclones are transformed to a mixture of diacylstilbenes and α-pyrones, when they are heated in diphenylether saturated with oxygen.

  当四旋风在氧饱和的二苯醚中加热时，它们会转化为二酰基二苯乙烯和 α-吡喃酮的混合物。

  The oxidation of mixtures of diarylacetylene ArCa parts per thousand CAr and Ar'Ca parts per thousand CAr' in a system CF3CO2H-CH2Cl2-PbO2 (0A degrees C, 1.5 h) results in products of cross-dimerization, (Z)-1,2,3,4-tetraarylbut-2-ene-1,4-diones Ar(ArCO) C=C(COAr')Ar'. The routes of transformation of intermediate cation-radicals of diarylacetylenes [ArCa parts per thousand CAr](+center dot) into the final products of oxidative dimerization are elucidated. By cyclic voltammetry and ESR spectroscopy the high reactivity of the diarylacetylene cation-radicals is demonstrated, the character of their singly occupied molecular orbitals (a(2) or b(1)) has been revealed by ESR method.
