The reaction of two-coordinated (trimethylsilylamino)phosphines (Me3Si)2NPESiMe31 (E = N) and 2 (E = CH) with hydroxycarbonyl compounds proceeded with four- or five-member heterocyclization to yield derivatives of oxaphosphetane, oxaphospholanes, and oxaphospholes. The reaction rate depends on the structure of hydroxyketones as well as on the type of the two-coordinated phosphorus compound in accordance
二配位(三甲基甲硅烷基氨基)膦 (Me3Si)2NPESiMe31 (E = N) 和 2 (E = CH) 与羟基羰基化合物的反应通过四元或五元杂环化反应生成氧杂膦、氧杂膦和氧杂磷的衍生物。根据 P=N 和 P=C 键的极性,反应速率取决于羟基酮的结构以及双配位磷化合物的类型。因此,在邻羰基苯氧基衍生物与膦 1 的情况下,反应在 30 分钟内完成,但在烷基羟基羰基的情况下需要 2 小时。与膦 2 的所有反应大约需要 24 小时。© 2004 Wiley Periodicals, Inc. 杂原子化学 15:413–417, 2004; 在线发表于 Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002/hc.20033
