Versuchsvorschrift

A Fischer-Porter test tube size aerosol compatibility vessel is fitted with a tee and valves to maintain a nitrogen atmosphere. A heptane solution of butyl ethyl magnesium (25 mL, 16 mMoles) and hexamethyl disilazane (3.3 mL) are injected by syringe into the tube. Gas is evolved when the two reactants are contacted. After 1 hour and 40 minutes at room temperature, the contents of the tube are transferred to a flask for solvent evaporation without exposing the contents to air. After about four hours at room temperature, with a N2 flow, crystals began to appear in the viscous residue. The following day, the residue appears to be completely solidified. A vacuum is applied for two hours to remove any volatiles.
