Storage and transfer of organomagnesium compounds safety precautions

4 Storage and transfer of organomagnesium compounds safety precautions 

Transfer of organomagnesium solution under inert atmosphere A, storage flask B, receiving flask C, inert gas in D, transfer tube E, sleeve F, to bubbler. 

For intermediate storage, modified Schlenk tubes (Fig. 2.7) may be used. The version with a burette side-arm is particularly convenient for dispensing a measured volume to a reaction vessel. 

For small-scale transfer the syringe-and-septum method is routinely used. The following procedure is recommended  

Typical assembly for an organomagnesium reaction. For reactions in boiling solvent the thermometer is replaced by a condenser.
