General description
http://www.sigmaaldrich.com/ifb/acta/v35/acta-vol35-2002.html#32
Application
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.
Other Notes
本品冷却储藏时可能会变浑浊，不影响使用
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.
