Reacție Sakurai

Reacția Sakurai sau reacția Hosomi-Sakurai este o reacție organică ce are loc între carbon-electrofili (precum o cetonă) și aliltrimetilsilan, fiind catalizată de un acid Lewis tare.^[1]^[2]^[3]^[4]^[5]^[6]^[7] Reacția a fost denumită după chimiștii japonezi Akira Hosomi și Hideki Sakurai.
