Abstract
(3 + 2)-Annulation of donor-acceptor cyclopropanes to alkynes induced by both Lewis and Brønsted acids has been developed. The reaction provides a rapid approach to functionalized indenes displaying intense visible emission (λmax = 430 nm, Φ = 0.28-0.34).
摘要
（3 + 2）-环丙烷的供体-受体的稠环化反应已经被开发出来，该反应可以通过路易斯酸和布朗斯特酸共同诱导炔烃发生。该反应为功能化茚提供了一种快速的方法，显示出强烈的可见发射（λmax = 430nm，Φ = 0.28-0.34）。
