Dimethylpropyl magnesium Chloride

The reaction soon continues to reflux without external heating and the 

The reaction mixture is filtered into B-2 (Fig. 1) and the magnesium salts extracted with solvent that has been condensed back into B-l.10 Three such extractions yield a final wash that is essentially colorless. The solvent is then condensed back into B-l, and the solvent and suspended magnesium salts
