在铜催化剂存在下,分别以B-2(pin)(2)和甲酸酯作为硼源和甲酰基源进行联烯的硼化反应。该反应选择性地以良好至高产率提供相应的-硼基-不饱和醛。此外,以甲酸酯和PhMe 2Si-B(pin)为硅源,实现了联烯的硅化。
The boraformylation of allenes with B-2(pin)(2) and a formate ester as boron and formyl source, respectively, proceeds in the presence of a copper catalyst. The reaction selectively affords the corresponding -boryl ,-unsaturated aldehydes in good to high yields. Furthermore, the silaformylation of allenes was achieved with a formate ester and PhMe2Si-B(pin) as the silicon source.
