Grignard Synthesis
Conversion of Cyclohexyl bromide to Cyclohexane
INTRODUCTION
The Grignard reagent is one of the most versatile substances in organic chemistry. The reagent is produced by reacting an alkyl halide with magnesium metal in ether. The reagent is then added to an acidic substance to produce an array of final products. In this experiment an alkyl halide will be converted to an alkane.
PROCEDURES
Week one of this exercise will involve the generation of the Grignard reagent, and then its reaction with an acidic solution. Week two will be the separation and purification of the product and its characterization.
Week One
The limiting reagent is 10.0 ml of cyclohexyl bromide.
Add the cyclohexyl bromide to a separatory funnel and add 15.0 ml of anhydrous ether.
Fit the round bottom flask with a three way adapter. Attach a condenser to the arm directly above the flask and the separatory funnel to the other arm.
Clamp the neck of the round bottom and use a lab jack to bring the heating mantle to the round bottom. Have an ice bath ready to moderate the rate of the reaction.
Initiate the reaction by letting half of the cyclohexyl bromide/ether mixture run into the round bottom flask.
Alternately heat the flask and pull the heat away until the reaction proceeds on its own.
Continue the reaction until all but the excess of magnesium is used up.
Cool the Grignard in the ice bath.
Add the Grignard slowly to a beaker containing 20.0 ml of 6 M HCl and two ice cubes. Cool this mixture in an ice bath.
Allow the reaction to finish, and then transfer the mixture to a glass jar, label it and store it in the refrigerator.
Week Two
Calculate the theoretical yield of cyclohexane based on the limiting reagent.
Determine, based on physical properties, where the cyclohexane is in the mixture.
Develop a plan to recover and purify the cyclohexane.
Have your plan reviewed by the instructor before beginning.
Implement your plan.
Determine your actual yield of cyclohexane.
Measure as many physical properties of the product as possible.
Run the IR of cyclohexyl bromide and your product.
