摘要：

(Chemical Equation Presented) Two plus one makes three-membered rings in an unusual [2+1] cycloaddition of phenylethyne with norbornadiene as catalyzed by a new palladium(II) complex with phosphinous acid ligands (see scheme). A related complex (cyclohexyl replaces tBu) efficiently catalyzes the [2+1] cycloaddition of norbornene derivatives with various terminal alkynes to provide functionalized exo-alkylidene-cyclopropanes. © 2005 Wiley-VCH Verlag GmbH & Co.
