The Lewis Base Stabilized Parent Arsanylborane H2AsBH2⋅NMe3

Abstract

Exclusively hydrogen-substituted arsanylboranes: The synthesis of the unprecedented Lewis base stabilized monomeric parent compound of the arsanylborane H2AsBH2⋅NMe3 was achieved in a one-pot reaction in high yield and purity. The analogous phosphanylborane was synthesized in a similar manner. A series of different reactions was performed on H2AsBH2⋅NMe3 to show its broad reactivity pattern.

Keywords: Group 13/15 compounds; Lewis acid base adducts; arsenic; boron; phosphorus; primary arsine.
