摘要

用镁对二氯膦进行还原脱卤反应，用相邻氯硅官能化的二膦和氨基二膦的[2+2]环二聚化反应去除氯三甲基硅烷，可以得到大量的氨基四膦。报道并讨论了几种四磷酸烷的分子结构。根据外环配体的大小和电负性，四元环的扭转角在22,5 ~ 45,7之间变化。

Synthese und Struktur aminosubstituierter Tetraphosphetane

A number of aminotetraphosphetanes could be obtained by reductive dehalogenation of dichlorophosphines with magnesium as well as by elimination of chlorotrimethylsilane from vicinal chlorosily-functionalized biphosphines and from [2+2]-cyclodimerization of aminodiphosphenes, respectively. The molecular structures of several tetraphosphetanes are reported and discussed. The torsion-angle of the four-membered rings varies from 22,5 to 45,7 depending on the size und electronegativity of the exocyclic ligands.

期刊介绍： Zeitschrift fuer Naturforschung B (ZNB) publishes novel research in all areas of inorganic chemistry, organic chemistry, and analytical chemistry. In particular, the journal focuses on solid state chemistry, coordination chemistry, main group element chemistry, synthetic organic chemistry, natural product chemistry and, to a lesser extent, on analytical chemistry. For more than 65 years Zeitschrift fuer Naturforschung B has been open to contributions from all fields of experimental and theoretical chemistry. Zeitschrift fuer Naturforschung B publishes 12 issues per volume/year. Sometimes double issues occur. Topics Solid state chemistry Coordination chemistry Main group element chemistry Organic chemistry Natural product chemistry.
