Abstract
The pyrimidines (4) are isolated from the products of photolysis of the sulphimides (1) and of the tetrazoles (2); pyrolysis of the tetrazoles gives benzimidazoles (5) in addition to the pyrimidines, the formation of these products being rationalised by mechanisms involving successive [1,5] or [1,9] shifts in 3aH-benzimidazole intermediates.Keywords
