Beschreibung

Anwendung

Convenient, salt-free, stable solution of a chiral allyl borane for asymmetric allylation of aldehydes leading to chiral homoallylic alcohols.[1][2]

Sonstige Hinweise

Material may become hazy upon cooler storage, this will not affect use

Under refrigerator storage, these salt-free, Ipc₂B(allyl) reagents do not show any appreciable decrease in selectivity is observed after several months. They exhibit excellent reactivity and reactions can be performed at 5°C, even in water.[3]
