Abstract

AbstractThe controlled hydrolysis of heteroleptic magnesium amide, LMgN(SiMe3)2 (L = CH[C(Me)N(2,6‐iPr2C6H3)]2) with water afforded the corresponding hydroxide [LMg(OH)·THF]2 as air and moisture sensitive compound. The presence of a sterically bulky β‐diketiminate ligand prevents the self‐condensation reaction of this hydroxide complex. Single crystal X‐ray analysis shows that the hydroxide is dimeric in the solid state. Reaction of the magnesium amide or LMg(Me)·OEt2 with LAlMe(OH) generates the heterobimetallic species containing the Mg–O–Al moiety. Additionally, the reaction of methylmagnesiumchloride with the free ligand leads to complex L′MgCl (L′ = CH[Et2NCH2CH2N(CMe)]2). As revealed by the crystal structure, L′MgCl is a solvent free monomeric magnesium chloride complex that is analogues to the Grignard reagent.
