Abstract
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
