Multicolor single-analyzer high-energy-resolution XES spectrometer for simultaneous examination of different elements.

The present work demonstrates the performance of a von Hámos high-energy-resolution X-ray spectrometer based on a non-conventional conical Si single-crystal analyzer. The analyzer is tested with different primary and secondary X-ray sources as well as a hard X-ray sensitive CCD camera. The spectrometer setup is also characterized with ray-tracing simulations.

2-(Dimethylamino)phosphinine: A Phosphorus-Containing Aniline Derivative.

The yet unknown 2-amino-substituted λ ,σ -phosphinines are phosphorus-containing aniline derivatives. Calculations show that the strong interaction of the π-donating NR  group with the aromatic system results in a high π-density at the phosphorus atom. We could now synthesize 2-N(CH ) -functionalized phosphinines, starting from a 3-N(CH ) -substituted 2-pyrone and (CH ) Si-C≡P.

Janus bis(NHCs) tuned by heteroatom-bridge oxidation states.

Synthesis of the first tricyclic bis(carbenes) with facially opposed imidazole-2-ylidenes and two linking phosphorus centres in different oxidation states is presented using a modular, high-yield synthetic route. The formation of homo bimetallic coinage metal complexes provides a glimpse on their potential use.
