Preparation of Me3CCN
Reacting Me3CMgBr with ClCN is the best method for the preparation of Me3CCN. This reaction involves the use of the Grignard reagent, Me3CMgBr, which is a strong nucleophile and reacts with ClCN to form Me3CCN.
Steps Involved
The reaction proceeds through the following steps:
1. Formation of the Grignard reagent: Me3CMgBr is prepared by reacting Me3CBr with Mg in ether.
2. Reaction with ClCN: Me3CMgBr is then reacted with ClCN in dry ether to form Me3CCN.
3. Workup: The reaction mixture is then treated with dilute acid to hydrolyze any unreacted Grignard reagent and to protonate the product, Me3CCN.
Mechanism
The reaction mechanism involves the attack of the nucleophilic carbon atom of the Grignard reagent on the electrophilic carbon atom of ClCN. This leads to the formation of an intermediate, which then undergoes hydrolysis to form the final product, Me3CCN.
Advantages of this method
1. High yields: This method gives high yields of Me3CCN.
2. Mild conditions: The reaction conditions are relatively mild, and the reaction can be carried out at room temperature.
3. Availability of reagents: The reagents used in the reaction, Me3CBr, Mg, and ClCN, are readily available and inexpensive.
4. Versatility: The Grignard reagent, Me3CMgBr, can be used for the preparation of a variety of other organic compounds.
Thus, the reaction of Me3CMgBr with ClCN is the best method for the preparation of Me3CCN.
