The title cyclic adducts have been reported to be 4-aryl-2,3,3-triphenyl-1,2-oxaphosphetane 2-oxides. However, these compounds are concluded not to be the 1,2-oxaphosphetanes, but 1-aryl-3,4-diphenyl-3,4-dihydro-1H-2,3-benzoxaphosphorin 3-oxides from our detailed NMR studies and the investigation of the chemical behavior of the adduct of benzaldehyde.
标题的环加成物已被报道为4-芳基-2,3,3-三苯基-1,2-氧
磷杂环烷 2-氧化物。然而,根据我们详细的NMR研究和对
苯甲醛加成物
化学行为的研究,这些化合物被认为不是1,2-氧
磷杂环烷,而是1-芳基-3,4
-二苯基-3,4-二氢-1H-2,3-苯并氧
磷杂环烷 3-氧化物。
