Grignard reagents are air-and moisture-sensitive. List at least threereactants, solvents, and/or techniques that were utilized in the experimental procedure to minimize exposure of the reactants to air and/or moisture.
Grignard reactions reacts with water forming alkanes.
The water present causes the reagent to decompose rapidly.
So, the solvents which are utilized in the experimental procedure to minimize exposure of the grignard reagents to air and/ormoisture are solvents such as anhydrous diethyl ether or tetrahydrofuran(THF), poly(tetramethylene ether) glycol (PTMG).
The reason for the use of these solvents is the oxygen present in these solvents stabilizes the magnesium reagent.
