A polyphosphide of the type (NaP) X 1 was obtained from red phosphorus and sodium in presence of small amounts of naphthalene in 1,2‐dimethoxyethane as solvent. 1 reacts with alkyl halides in dependence on the kind of alkyl group with formation of different alkylcyclophosphanes. As definite compounds Me 5 P 5 2 , Et 5 P 5 3 (with not definite constitution), i‐Pr 4 P 4 4 and t‐Bu 4 P 4 5 could be isolated. 1 was identified by X‐ray diffraction, 2 – 5 by means of their 1 H, 13 C, 31 P n.m.r. and mass spectra. The molecular structure of 4 was identified by electron diffraction.
