| Abstrakt: |
Oxidation of solutions of 4H-thiopyrans and 4H-selenopyrans to the corresponding heteroaromatic cation bromide occurs on irradiation with ultraviolet light in the presence of CBr4. Reaction takes place by a free radical chain mechanism. The presence of CHBr3 and C2Br6 in the reaction mixture was detected chromatographically. [ABSTRACT FROM AUTHOR] |
