Contributions to the Chemistry of Phosphorus, 211. - Pentaisopropyltetracycloundecaphosphane, P11iPr5 - Preparation and Structure Determination by Nuclear Magnetic ResonancePentaisopropyltetracycloundecaphosphane (1) has been obtained by reaction of iPrPCl2 with P4 and magnesium and subsequent thermolysis of the crude reaction product, and has been isolated in 91% purity. According to NMR-spectroscopic investigations, 1 has a constitution analogous to that of the hydrocarbon 2,8-ethanonoradamantane, thus being 3,4,7,9,11-pentaisopropyltetracyclo[6.2.1.02,6.05,10]undecaphosphane Compound 1 is formed as a mixture of two configurational isomers 1a and 1b, which differ from each other in their spatial arrangements of the isopropyl groups at P3 and P4.
