Reaction Steps

In an argon atmosphere, a dilithium(N,N′-di-sec-butyl-1,2-vinylenediaminide) solution prepared according to the procedure and reagent quantities described in Reference Example-8 was added to a hexane (150 mL) solution containing 25.00 g (184.6 mmol) of trichlorosilane, and the mixture was stirred at room temperature for 6 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: 85° C./5×102 Pa) to obtain 2-chloro-1,3-di-sec-butyl-1,3-diaza-2-silacyclopent-4-ene (Si(sBuNCHCHNsBu)(H)Cl) as a pale yellow liquid (yielded amount: 18.10 g, yield: 42%). This product was a mixture of a plurality of isomers differing in the steric configuration from each other.
