Magnesium Grignard reagents

There is a large series of lithium alkyls and lithium aryls which are useful m organic chemistry in much the same way as the magnesium Grignard reagents. Unlike Na, K, Rb, or Cs, but like Mg, lithium reacts directly with nitrogen to form a nitride ... 

Metathesis reactions are common in the preparation of organic derivatives of elements, using organo-lithium or -magnesium (Grignard) reagents produced by direct synthesis ... 

Under MVS conditions with which even Phi-reacts with magnesium. Grignard reagent yields are low. The reaction scheme 7] includes the possible role of clusters in MVS reactions, but does not explain the low Grignard reagent yields. 

Most organometallic compounds will react in some way with carbonyl groups, but in this section, we will confine the discussion to magnesium (Grignard reagents are very important), lithium, cadmium, zinc, and copper.
