45_40/2006Cover Picture: A Melt Approach to the Synthesis of catena-Phosphorus Dications To Access Derivatives of [P6Ph4R4]2+ (Angew. Chem. Int. Ed. 40/2006)

A new melt approach has enabled the synthesis of the first catena-hexaphosphorus dications, as described in the Communication by N. Burford, J. J. Weigand, and co-workers on page 6733 ff. The cover picture (by Jared MacPherson) shows a photograph of the reaction melt of 4/5 (PhP)5, 2 Ph2PCl, and 2 GaCl3 at 100 °C, which solidifies to yield [P6Ph8][GaCl4]2 quantitatively upon further heating. Such cations represent a new direction in phosphorus chemistry and promise a parallel to catena-carbon (organic) chemistry.

Solid-phase synthesis produces lipid-modified peptides that can be chemoselectively ligated onto proteins. In their Review on page 6622 ff., H. Waldmann and co-workers discuss unsolved questions about the Ras-superfamily GTPases.


Porous Materialsfor002

In their Communication on page 6648 ff., J. L. Hedrick and co-workers describe the preparation of organosilicate monoliths and nanoparticles by solvent-directed self-assembly. By changing the deposition solvent, a single block copolymer/organosilicate mixture can generate widely different nanostructures.


Supramolecular Chemistryfor003

J. F. Stoddart, D. J. Williams, and co-workers introduce a new class of mechanically interlocked molecular compounds called “suitanes” in their Communication on page 6665 ff., and discuss the template-directed synthesis of the simplest member of this series, suit[2]ane.
