DOI: 10.6023/cjoc202308009 Abstract (287) HTML (17) PDF (714KB)(315) Knowledge map Regioselectivity adjustment is one of the key research fields in organic chemistry, and electronic effect is the key factor for adjustment. In this work, density functional theory (DFT) calculation was carried out to investigate how electronic effect of substituent affects regioselectivity in the reductive elimination step. Palladium-catalyzed annulation of silacyclo- butanes and 2-iodobiarenes was selected as model reaction, and detailed reaction mechanism is illustrated. The results shows that the reaction undergoes Pd—I bond oxidative addition, concerted metalation deprotonation (CMD), Pd—Si bond oxidative addition, and reductive elimination process to synthesize eight-membered silacycles, and C—Si bond reductive elimination is the rate determining step. Study of electronic effect in Pd(IV) reductive elimination transition state shows that when asymmetrically substituted 2-iodobyphenyl is used as substrate, electron density of aromatic ring is the main factor to control regioselectivity. Groups with higher electron density have higher priority for reductive elimination, and this is in accordance with electron flow in this elementary reaction.
