Methylgallium dichloride → Bis-(3-dimethylaminopropyl)methylgallium

Participants

Reaction Steps

5 g of 3-dimethylaminopropyllithium (53.7 mmol) are suspended in 40 ml of pentane, and a solution of 4 g of methylgallium dichloride (25.7 mmol) in 20 ml of benzene is added dropwise. The mixture is first stirred at room temperature for one hour and then boiled under reflux for 6 hours. After cooling, the lithium chloride and excess lithium salt are filtered off and the solvent is stripped off in vacuo. The residue which remains is sublimed in vacuo at an oil bath temperature of 60° C. Bis-(3-dimethylaminopropyl)methylgallium is obtained as a white solid of melting point 52° C.
