반응 단계

Bis(t-butylamino)silacyclobutane (BTBSCB) was synthesized by reacting 1,1-dichlorosilacyclobutane with an excess amount of t-butylamine (Equation 1). To do so, 19.7 ml (0.166 mol) 1,1-dichlorosilacyclobutane was added to 105 ml (0.999 mol) t-butylamine in 1 L hexanes at 0° C. After bodying for three days at the room temperature, the reaction slurry was filtered to remove t-butylamine hydrochloride salt. The filtrant was vacuum dried to give a crude liquid product which was then vacuum distilled. 16 g Product was isolated at 99.2% purity in 45% yield at 71° C. under 50 torr pressure. The structure of the product analyzed with 1H, 13C and 29Si NMR, FT-IR and GC-MS was in consistence with bis(t-butylamino)silacyclobutane.
