The
tris[(1-isopropylbenzimidazol-2-yl)dimethylsilyl]methyl thallium
compound, [TismPriBenz]Tl, reacts with Li, Na,
K, and Rb to afford the respective alkali metal carbatrane complex,
[TismPriBenz]M (M = Li, Na, K, and Rb), while
the cesium complex [TismPriBenz]Cs is obtained
via the reaction of [TismPriBenz]Li with CsF.
These carbatrane compounds [TismPriBenz]M (M
= Li, Na, K, Rb, and Cs) constitute the first complete series of structurally
characterized monomeric alkyl compounds of the nonradioactive alkali
metals.
