A Dimethylgallium Boryl Complex and Its Methyllithium Addition Compound.

The three-coordinate complex MeGa[B-(NArCH)] (Ar = CHiPr-2,6) is accessible via a tandem Lewis acid-base metathesis protocol employing (THF)Li[B(NArCH)] and GaMe. It features a very short Ga-B bond of 2.067(3) A, which was further investigated by DFT calculations and the analysis of the electron den...

Sumario:The three-coordinate complex MeGa[B-(NArCH)] (Ar = CHiPr-2,6) is accessible via a tandem Lewis acid-base metathesis protocol employing (THF)Li[B(NArCH)] and GaMe. It features a very short Ga-B bond of 2.067(3) A, which was further investigated by DFT calculations and the analysis of the electron density. Reaction of MeLi with MeGa[B- (NArCH)] forms tetrameric [LiMeGa{B(NArCH)}] with a "nanowheel" structure.
