Contributions to the Chemistry of Phosphorus, 211. – Pentaisopropyltetracycloundecaphosphane, P 11 iPr 5 – Preparation and Structure Determination by Nuclear Magnetic Resonance Pentaisopropyltetracycloundecaphosphane ( 1 ) has been obtained by reaction of iPrPCl 2 with P 4 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[6.2.1.0 2,6 .0 5,10 ]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 P 3 and P 4 .
