A series of fluorinated polyolefins has been efficiently synthesized via the copolymerization of ethylene with 5-(perfluoro-n-alkyl)norbornenes by employing a class of [ONS] titanium catalysts, which possess an open coordination space environment and exhibited excellent tolerance to fluorine atom and excellent catalytic activity (up to 1....

A new regioselective method for the synthesis of multifunctionalized indoles from [3 + 2] annulation of 2-bromocyclopropenes with anilines has been developed. By employing a nickel complex as a catalyst, 27 examples of indole products were obtained in good yields with excellent regioselectivity. Synthetic utility of the resulting product ...

In the presence of 4 Å MS, both all-alkene [2 + 2 + 2] and [2 + 2] cyclizations of dimethyl methylenemalonate (DMM) with N-sulfonyl enamides were selectively achieved under In(OTf)3 and Cu(OTf)2 catalysis, respectively. In(OTf)3-catalyzed [4 + 2] cyclization of the sulfonylamidocyclobutanes with another molecule of DMM or other...

A selectivity switch in a RhII/carbene‐triggered cyclopentannulation with catalytic InCl3 is reported for the first time, affording both diastereomers of the fused spiroindolines and an unusual bridged tetracyclic indoline in high yields with excellent selectivities. Mechanistic studies indicate an intramolecular annulation of the indole...
