High‐Pressure Synthesis of Nitrogen‐Rich Y(N5)3·N2 Pentazolate with Perovskite Topology

open access: yesAngewandte Chemie International Edition, EarlyView.
Yttrium pentazolate, Y(N5)3·N2, with an exceptionally high nitrogen‐to‐metal ratio of 17:1 and perovskite topology, was synthesized from yttrium and nitrogen at 125 GPa and 3000 K in a laser‐heated diamond anvil cell. Abstract The discovery and stabilization of the cyclo‐N5⁻ anion have introduced a class of pentazolate compounds with significant ...

Reactivity of Pnictaalumenes Towards 1,3‐Dipole Molecules

open access: yesAngewandte Chemie International Edition, EarlyView.
Pnictaalumenes with a Pn═Al multiple bonds undergo azide or diazoalkene insertions rather than [3+2] cycloadditions. This results in AlN2P heterocycles, which show a great structural variety depending on the sterics of the azide. With TMS‐diazoalkane, thermal rearrangements afford rare cyanidoaluminates. Abstract Alkynes undergo 1,3‐dipolar cyclization
