The synthesis and isolation of the first complex with a nucleophilic boryl anion, (THF)2Li{B(NArCH)2} (Ar=2,6-diisopropylphenyl), back in 2006 by Segawa et al has triggered considerable research with the aim of generating unprecedented metal-boron bonds. Herein, we investigated the accessibility and reactivity of aluminum and gallium derivatives featuring this very boryl ligand. The X-ray structure analyses of dimeric [Me2Al{B(NArCH)2}]2 and monomeric Me2Ga{B(NArCH)2} will be presented and the imponderabilites of ate complexation be addressed. Moreover, the reactivity of such Group 13 boryls toward organolanthanide complexes will be assessed.
