N2  - Photooxidation  in the solid state of tetrabromofuran (1) gave the tetrabromo -&#947;-lactone (2) (30%), but in benzene solution gave dibromomaleic anhydride (3) (85%). Possible radical chain mechanisms for the transformations (1) &#8594; (2) and (1) &#8594; (3) are suggested. A molecular orbital discussion attempts to explain how an initial &#960;-&#960;* transition of a C=C bond in (1) leads to a &#963; C-Br bond fission. Use of e.p.r . to detect radicals in the transformations (1) &#8594; (2) and (1) &#8594; (3) failed.
