Main group chemistry is represented in Chapter 1, where O Hara and coworkers have provided an update on the structural diversity of alkali metal magnesiates, a field of growing interest not only from the structural but also from its synthetic point of view. [Pg.389]

Magnesium amides can form a wide range of mixed metal amido complexes with alkali metal ions (M2[Mg(NH2)4]) (M = K, Rb or Cs).These contain tetrahedral Mg-centered [Mg(NH2)4] ions connected in three-dimensional networks by coordination of the amido groups to the group 1 metal ions. The most common hetero metal is lithium and lithium amido magnesiates are readily accessible by the addition of a lithium amide to a magnesium amide. [Pg.52]

A variety of alkali metal and metallocene-containing magnesium amides are known. Thus, attempted metallation of ferrocene using potassium tris(amido)magnesiate KMg N-(SiMe3)2 3 unexpectedly led to n-coordination of neutral ferrocene moieties to a pota-... [Pg.55]

Not only magnesium amides but also magnesiate bases can be used for the preparation of organomagnesium derivatives or even dimagnesiated species via alkali-metal-mediated metaUations [35]. [Pg.370]
