Preparation of Rieke Magnesium Using Potassium or Sodium as Reducing Agent

Preparation of Rieke Magnesium Using Potassium or Sodium as Reducing Agent 

A 200 ml three-necked round-bottomed flask equipped with a Teflon-coated magnetic stirring bar, rubber septum, and condenser connected to an argon inlet is charged with 1.5 g (0.038 g.-atom) of freshly cut potassium, 2.01 g (0.0211 mol) of anhydrous magnesium chloride, 3.55 g (0.0214mol) of anhydrous potassium 

Preparation of a Grignard Reagent Using Rieke Magnesium Prepared Using Potassium-Potassium iodide 1-Norbornanecarboxyi Acid 

The mixture of active magnesium metal and potassium salts as prepared before is allowed to cool to room temperature, after which 1.25 g (0.00958 mol) of 1-chloronorborane is injected with a syringe through the septum into the flask.
