of natural heterocyclic compounds, coumarin and chromene. The major products (>70%) are 4-aryl-7-tert-butyl-2,6-dichloro-, 4-aryl-2-bromo-7-tert-butyl-, and 4-aryl-7-tert-butyl-2-fluoro-1,2λ5-benzoxaphosphinine 2-oxides. Hydrolysis of these compounds and their treatment with amines gives the corresponding 2-hydroxy and 2-amino derivatives, as well as ammonium salts. The structure of some compounds was
5-反应叔丁基-2,2,2-三氯乙基,2,2,2-三溴-5-叔丁基-和2,2-二溴-5-叔丁基-2-氟-1- ,3,2λ 5 -benzodioxaphospholes与芳基-和alkylacetylenes导致2-卤代1,2λ的定量形成5 -benzoxaphosphinine 2氧化物,其可以被认为是天然的杂环化合物,香豆素和色烯的磷类似物。主要产品(> 70%)为4-芳基-7-叔丁基-2,6-二氯-,4-芳基-2-溴-7-叔丁基-和4-芳基-7-叔-丁基-2-氟- 1,2λ 5-苯并氧杂膦酸2-氧化物。这些化合物的水解及其用胺的处理产生相应的2-羟基和2-氨基衍生物以及铵盐。X射线分析证实了某些化合物的结构。
