53_21/2014Cover Picture: Silver(I)-Catalyzed Hydroazidation of Ethynyl Carbinols: Synthesis of 2-Azidoallyl Alcohols (Angew. Chem. Int. Ed. 21/2014)

The hydroazidation of unactivated alkynes is described by X. Bi and co-workers in their Communication on page 5305 ff. Silver catalysis enabled the chemo- and regioselective transformation of ethynyl carbinols into vinyl azides. A wide variety of 2-azidoallyl alcohols were obtained in good to excellent yields. The synthetic utility of 2-azidoallyl alcohols was demonstrated by further transformations into NH aziridines.

Heterolytic H2 Cleavage

A synthetic model complex of an iron hydrogenase was used by Bullock et al. on page 5300 ff. to investigate the heterolytic cleavage of H2 using neutron diffraction.for001

Boron Radicalsfor002

A borolyl anion undergoes single-electron-transfer (SET) processes in its reaction with triorganotetrel halides. In their Communication on page 5453 ff., H. Braunschweig and co-workers describe the first isolation of a neutral borole radical along with far-reaching synthetic implications.


Magnetic Anisotropyfor003

E. J. L. McInnes et al. show in their Communication on page 5310 ff. that the antisymmetric component of the electronic exchange interaction (also known as Dzyaloshinski–Moriya exchange) is responsible for the large magnetic anisotropy in the S=5/2 ground state of a trimetallic complex.
