The quest for cyaphide, the phosphorus equivalent of cyanide, has been a challenge for many years. In their Communication on page 6159 ff., H. Grützmacher and co-workers describe their approach to prepare the first stable terminal cyaphide complex [RuH(CP)(dppe)2] (dppe=bis(1,2-diphenylphosphinoethane)). In an initial silyl-protected complex, the Ru center was P-coordinated by the C≡P ligand. Removal of the silyl group yielded the C-coordinated Ru complex, whose structure is shown on the cover picture.

One of the decisive steps in the synthesis of many natural products is a macrocyclization by ring-closing matathesis. J. Pérez-Castells and A. Gradillas describe in their Minireview on page 6086 ff. the conditions that are advantageous for this reaction.

Multiplex Analysisfor002

Though not well known, suspension systems of coded microspheres are potentially far better suited for multiplex analysis than the established planar-array techniques. R. Wilson and co-workers describe this new approach and its advantages in their Review on p. 6104 ff.

In their Communication on page 6118 ff., S. Aldridge, C. Jones, and co-workers present a cationic terminal amino borylene complex that displays delocalized Fe-B-N bonding and undergoes [4+1] cycloaddition with an ortho-benzoquinone.
