P analogues of cyclohexane: The first examples of hexaphosphorus homocyclic dications [P6Ph4R4]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. (Figure Presented). 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
