**2.5 Metal exchange reaction**

This is an interesting route for the preparation of simple metal to carbon bond. The sample below shows a common metal interchange reaction [10].

$$\text{CH}\_3(\text{CH}\_2)\_3\text{-Li} + \text{KOC}(\text{CH}\_3)\_3 \rightarrow \text{CH}\_3(\text{CH}\_2)\_3\text{-K} + \text{LiOC}(\text{CH}\_3)\_3\text{-K}$$
