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 t Bu) efficiently catalyzes the [2+1] cycloaddition of norbornene derivatives with various terminal alkynes to provide functionalized exo ‐alkylidenecyclopropanes.
