Treatment of olefins bearing a directing group with alpha,beta-unsaturated carbonyl compounds, alkynes, or aldehydes in the presence of a catalytic amount of a rhenium complex, ReBr(CO)(3)(thf) gave gamma,delta-unsaturated carbonyl compounds, dienes, and allyl silyl ethers, respectively. This reaction proceeds via C-H bond activation, insertion of unsaturated molecules into the formed rhenium-carbon bond, and then reductive elimination (or transmetalation in the case of aldehydes).
在催化量的铼配合物[ReBr(CO)(3)(thf)]₂存在下，用α,β-不饱和羰基化合物、炔烃或醛处理带有导向基团的烯烃，分别得到γ,δ-不饱和羰基化合物、二烯和烯丙基硅醚。该反应通过C-H键活化、不饱和分子插入形成的铼-碳键，然后进行还原消除（或在醛的情况下进行转金属化）来进行。
