Benzimidazol-2-yl di- or tri-thiocarbonates and iso- or isothio-cyanates give, on heating in the presence of triethylamine, the novel [1,3,5]thiadiazino[3,2-a]benzimidazole-2,4(3H)-diones (11; X = Y = O) or their sulphur analogues (11; X = S, Y = O; or X = Y = S).
在三乙胺存在下加热,苯并咪唑-2-基二硫代或三硫代碳酸酯和异硫氰酸酯或异硫氰酸酯生成新型[1,3,5]噻二嗪[3,2 - a ]苯并咪唑-2,4 (3 H)-二酮(11; X = Y = O)或它们的硫类似物(11; X = S,Y = O;或X = Y = S)。
