An unprecedented (NH4)2S2O8 mediated metal-free three-componentalkene oxyalkynylation using H2O or alcohol as oxygenation agent is described. Mechanistic studies suggested that the reversed regioselectivity should be dictated by an alkene radical cation intermediate.
描述了前所未有的(NH 4)2 S 2 O 8介导的使用H 2 O或醇作为氧化剂的无金属三组分链烯氧基炔基化反应。机理研究表明,逆向的区域选择性应由烯烃自由基阳离子中间体决定。

ales generated from the corresponding propargylic acetals rearrange in the presence of borontrichloride thus opening an efficient and convenient route to a variety of homopropargylic alcohols free of the corresponding allenic isomers. Unexpectedly, the parent derivative leads exclusively to the allenic alcohol.
