Diethylamine → HCID 123172080, compound

Participants

Reaction Steps

In an argon atmosphere, a dilithium(N,N′-di-tert-butyl-1,2-vinylenediaminide) solution prepared by using 32.00 g of tBuNCHCHNtBu, 50 mL of tetrahydrofuran, 150 mL of hexane and 2.67 g of lithium according to the procedure described in Reference Example-9 was added to a hexane (120 mL) solution containing 25.20 g (186.0 mmol) of trichlorosilane, and the mixture was stirred at room temperature for 4 hours. To this reaction mixture, 30.00 g (410.2 mmol) of diethylamine was added, and the mixture was stirred at room temperature for 5 hours. Insoluble matters produced were separated by filtration, and the solvent was removed by distillation from the filtrate under atmospheric pressure. The obtained residue was distilled under reduced pressure (distillation temperature: 102° C./4.0×102 Pa) to obtain 1,3-di-tert-butyl-2-diethylamino-1,3-diaza-2-silacyclopent-4-ene (Si(tBuNCHCHNtBu)(H)NEt2) as a pale yellow liquid (yielded amount: 30.29 g, yield: 60%).
