A Dimethylgallium Boryl Complex and Its Methyllithium Addition Compound

The three-coordinate complex Me2Ga[B(NArCH)2] (Ar = C6H3 iPr2-2,6) is accessible via a tandem Lewis acid–base metathesis protocol employing (THF)2Li[B(NArCH)2] and GaMe3. It features a very short Ga–B bond of 2.067(3) Å, which was further investigated by DFT calculations and the analysis of the elec...

Description
Summary:The three-coordinate complex Me2Ga[B(NArCH)2] (Ar = C6H3 iPr2-2,6) is accessible via a tandem Lewis acid–base metathesis protocol employing (THF)2Li[B(NArCH)2] and GaMe3. It features a very short Ga–B bond of 2.067(3) Å, which was further investigated by DFT calculations and the analysis of the electron density. Reaction of MeLi with Me2Ga[B(NArCH)2] forms tetrameric [LiMe3Ga{B(NArCH)2}]4 with a “nanowheel” structure.
