The reaction of tris-crotyl-boron with vinylic olefins in the presence of triethyl-aluminium, results in the addition of an α-methylallyl group and an aluminium atom to the double bond, as indicated by the hydrolysis products. The stereochemical aspect of the reaction is discussed and a mechanism is proposed to explain the preferential formation of one diastereoisomer.
如水解产物所示,在三乙基铝的存在下三巴豆基硼与乙烯基烯烃的反应导致在双键上添加一个α-甲基烯丙基和一个铝原子。讨论了反应的立体化学方面,并提出了解释一种非对映异构体优先形成的机理。
