P analogues of cyclohexane : The first examples of hexaphosphorus homocyclic dications [P 6 Ph 4 R 4 ] 2+ (R=Ph, Me; see picture, P yellow, C dark gray) were prepared in a melt reaction from readily accessible starting materials in essentially quantitative yield. X‐ray analysis of the dications reveals cyclohexane‐like twist‐boat and chair conformations of the phosphorus homocycle in the solid state.
