摘要：

Heating of the lithium magnesate [Li(THF)2(mu-Br)2Mg(Tsi)(THF)] (Tsi = (Me3Si)3C) under vacuum gives the dialkylmagnesium compound Mg(Tsi)2, the first two-coordinate magnesium derivative to have been structurally characterized in the solid state. The compound is remarkably thermally stable, not decomposing (or melting) when heated to 350-degrees-C. It has a very low reactivity, failing to react in toluene with, for example, CO2, Me3SiCl, Me2SiHCl, MeI, BCl3 or CH3COCl, and even with neat CH3COCl at its boiling point. It does react, though fairly slowly, with I2 in toluene to give TsiI, and more rapidly with Br2 to give TsiBr, and with an excess of PhSO2Cl in toluene at 100-degrees-C to give TsiCl. It decomposes quickly in the air, and reacts readily with MeOH in toluene to give TsiH without formation of detectable amounts of the intermediate TsiMgOMe, and with O2 in toluene.
