Potassium cyanate → HCID 123671386, compound

Participants

Reaction Steps

In an argon atmosphere, 8.33 g (35.8 mmol) of Si(tBuNCHCHNtBu)(H)Cl was dissolved in 30 mL of tetrahydrofuran and after adding 3.19 g (purity: 96%, 37.8 mmol) of potassium cyanate, the mixture was stirred for 15 hours under heating and refluxing. 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./3.3×102 Pa) to obtain 1,3-di-tert-butyl-2-isocyanato-1,3-diaza-2-silacyclopent-4-ene (Si(tBuNCHCHNtBu)(H)NCO) as a colorless liquid (yielded amount: 7.07 g, yield: 83%). The thus-obtained Si(tBuNCHCHNtBu)(H)NCO was measured for the 1H and 13C NMR spectra, as a result, these spectra agreed with spectra of that obtained in Example-29.
