Part B Lithium and Grignard Reagents

We have learned so far in this course that R3C is very high in potential energy. It turns out that carbon does not form useful salts with the usual counterions (e.g., NaCHs and KCH3 have no synthetic utility). 

However, it does form usefiil salt-like reagents with some metals, including lithimn and magnesium. These are examples of organometallic reagents, so called because they have a metal-carbon bond.
