Further Investigations into the Synthesis and Characterization of Halo-Boron-Arsenic Compounds: X-Ray Crystal Structures of X3B · As(SiMe3)3(X = Cl, I) and [I2BAs(SiMe3)2]2

The Lewis Base Stabilized Parent Arsanylborane H2AsBH2⋅NMe3

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.
