Two new tetrameric phosphaalkynes , the isomers 1 and 3 , have been synthesized. The cyclotetramer 1 with a “central” P 4 unit forms in high yield by the demetalation of the zirconium compound 2 with [(Ph 3 P) 2 NiCl 2 ]. The isomer 3 , which contains two PC double bonds, is obtained as a by‐product in the reaction of 2 with hexachloroethane; the major product is the tetraphosphacubane 4 .
