Gold nanoparticles supported on TiO(2) (~1%) catalyse in high yields the selective cycloisomerisation of aryl propargyl ethers into the corresponding 2H-chromenes, under heterogeneous conditions. 2H,2'H-3,3'-Bichromenes resulting from a catalytic oxidative dimerization pathway are also formed as by-products.
负载在 TiO(2)（~1%）上的金纳米粒子在非均相条件下，高收率地催化芳基炔丙基醚选择性环异构化为相应的 2H-色烯。通过催化氧化二聚化途径生成的 2H,2'H-3,3'-联色烯也是作为副产物形成的。
