（3 + 2）-环丙烷在Lewis酸和Bronsted酸诱导下与炔烃发生环化反应。该反应提供了一种快速的方法来获得具有强烈可见光发射的功能化指数（lambda(max) = 430 nm, Phi = 0.28-0.34）。
(3 + 2)-Annulation of donor-acceptor cyclopropanes to alkynes induced by both Lewis and Bronsted acids has been developed. The reaction provides a rapid approach to functionalized indenes displaying intense visible emission (lambda(max) = 430 nm, Phi = 0.28-0.34).
