A new synthesis of unsymmetrical phosphinic acids R′P(O)OHR″ has been evaluated. The first P–C bond was formed by base-promoted H-phosphinate alkylation of a protected H-phosphinate, which is easier and safer to handle. A one-pot methodology was developed for the second P–C bond formation reaction that involves the sila-Arbuzov reaction. This methodology was then extended to the synthesis of a dialkylphosphinic
已经评估了不对称次膦酸 R'P(O)OHR" 的新合成。第一个 P-C 键是由受保护的 H-次膦酸盐的碱促进 H-次膦酸盐烷基化形成的,处理起来更容易、更安全。为涉及 sila-Arbuzov 反应的第二个 P-C 键形成反应开发了一种一锅法。然后将该方法扩展到具有氨基官能团的二烷基次膦酸的合成。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
