This paper reports the synthesis and characterization of a number of monocyclic systems with one or two phosphorus atoms in the scaffold. The cyclic systems with one P‐atom are: 1‐phosphacyclodeca‐3,8‐diyne, 1‐phosphacycloundeca‐3,9‐diyne, 1‐phosphacyclododeca‐3,10‐diyne, 1‐phosphacyclotrideca‐3,11‐diyne, 1‐phosphacyclotetradeca‐3,12‐diyne and 1‐phosphacyclotetradeca‐4,11‐diyne. The P‐centers in the rings were further stabilized by phenyl‐ or 2,4,6‐tri‐ tert ‐butylphenyl rings as third ligand and sulfur or oxygen atoms as fourth ligand. The rings with two P‐atoms are 1,8‐diphospha‐cyclotetradeca‐4,11‐diyne and 1,10‐diphosphacyclooctadeca‐5,14‐diyne, with phenyl rings and oxygen at the P‐centers. For many of the products the structures and conformations in the solid state were obtained by X‐ray studies.
