Descrição

Aplicação

This allylboration reagent is a convenient, salt-free, stable solution of a chiral allyl borane for asymmetric allylation of aldehydes leading to chiral homoallylic alcohols.

Outras notas

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.
