Abstract

In the presence of a catalytic amount of bismuth triflate and under microwave irradiation, mixtures of aldehyde and allylstannane afforded smoothly the corresponding homoallylic alcohol. A wide variety of aldehydes were treated under these conditions. The reactions proceeded rapidly and afforded smoothly the corresponding homoallylic alcohol in good to very good yields using catalytic amounts of Bi(OTf)~3~**·**4H~2~O (0.5 mol‐%) and under microwave irradiation for a short time.(© Wiley‐VCH Verlag GmbH & Co.
