Reaction Steps

In an argon atmosphere, a dilithium(N,N′-di-tert-butyl-1,2-vinylenediaminide) solution prepared according to the procedure and reagent quantities described in Reference Example-9 was added to a hexane (50 mL) solution containing 25.20 g (186.0 mmol) of trichlorosilane, and the mixture was stirred at room temperature for 3 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: 80° C./3.8×102 Pa) to obtain 2-chloro-1,3-di-tert-butyl-1,3-diaza-2-silacyclopent-4-ene (Si(tBuNCHCHNtBu)(H)Cl) as a colorless liquid (yielded amount: 35.58 g, yield: 83%).
