title: Lewis and Brønsted acid induced (3 + 2)-annulation of donor-acceptor cyclopropanes to alkynes: indene assembly.
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).
