Abstract

Mechanochemistry has great potential in the syntheses of low-valent Mg(I) complexes. Magnesium iodide precursors with three different beta-diketiminate (BDI) ligands of varying bulk have been reduced with K/KI (or Na/NaCI) using the ball-mill. Depending on the steric bulk of the ligand, the raw products are intensely colored powders, indicating the presence of (BDI)Mg center dot radicals. Extraction with pentane gave (BDI)Mg-Mg-(BDI) in excellent yields. Reaction of the powder with H-2 prior to extraction gave [(BDI)MgH](2). Extraction with benzene gave (BDI)Mg(C6H6)Mg(BDI) with a dearomatized puckered benzene dianion. Ball-milling in the presence of triphenylbenzene gave a dinuclear Mg complex with a Ph3C6H3-dianion which slowly decomposed to (BDI)Mg-Mg(BDI) and Ph3C6H3.
