  Symmetric hydrogen bonding in dimethylammonium hydrogen diphenyldiphosphonate

  摘要：

  In the title compound, C2H8N+center dot C12H11O5P2-, pairs of hydrogen diphenyl-diphospho-nate anions form dimers across a twofold axis, with two symmetric O center dot center dot center dot H center dot center dot center dot O hydrogen bonds [O center dot center dot center dot O = 2.406 (3) and 2.418 (3) angstrom]. The 12-membered ring thus formed has crystallographic 2 and quasi-222 symmetry. Cations on either side of the ring form N-H center dot center dot center dot O hydrogen bonds to the four extraannular O atoms, with N center dot center dot center dot O distances of 2.765 (2) and 2.748 (3) angstrom.

  Attempts to synthesise phosphinic amides for use as intermediates in the study of “metaphosphate” type compounds are described. In the case of phenyl phosphinic amides the attempts were defeated by the intermediate formation of phenylphosphinic anhydride which undergoes a facile and remarkable decomposition to give phenylphosphonic acid, tetraphenylcyclotetraphosphine, and phenylphosphine. The mechanism

  描述了在“偏磷酸盐”型化合物研究中尝试合成用作中间体的次膦酰胺的尝试。在苯基次膦酰胺的情况下，尝试被中间形成的苯基次膦酸酐打败了，该中间体经历了容易且显着的分解，从而生成了苯基膦酸，四苯基环四膦和苯基膦。根据苯基次亚膦的形成来讨论该反应的机理，但是试图证明这一点尚无定论。
