One less carbon atom is found in 1-halo-1-iodo compounds obtained by C1-C2 radical fragmentation of carbohydrate 1,2-halohydrins. This fragmentation is achieved via the anomeric alkoxy radicals of the halohydrins, formed upon reaction with (diacetoxyiodo)benzene and iodine [Eq. (1); X=Cl, Br, I].
在通过碳水化合物1,2-卤代醇的C1-C2自由基裂解获得的1-卤代-1-碘代化合物中,发现少一个碳原子。通过与(二乙酰氧基碘)苯和碘反应时形成的卤代醇的异头烷氧基自由基来实现这种断裂。(1); X = Cl,Br,I]。
