7-nitro-2-phenyl-1,2-benzisoselenazol-3(2H)-one leads to an abnormal behavior due to a dipole stabilisation between the nitro group and the selenium atom. The first ever synthesis of a 2,1-benzoxasetenol-3-one is described. The unexpected insertion of a sulfur atom from thionyl chloride results in the formation of the 7-nitro-2,1-benzothiaselenol-3-one .
由于硝基和硒原子之间的偶极稳定作用,导致7-硝基-2-苯基-1,2-苯并硒唑-3(2H)-一的合成导致异常行为。描述了2,1-苯并恶魔烯醇-3-酮的首次合成。来自亚硫酰氯的硫原子的意外插入导致形成7-硝基-2,1-苯并硫代噻吩酚-3-酮。
