Abstract

Abstract Stepwise palladium-catalyzed cross-coupling between terminal alkynes and vinyl triflates afforded the first cross-conjugated enyne macrocycles constructed of 3-alkylidene-1- propynyl [− C≡ C− C (= CR 2)−] building blocks, namely, the expanded radialene 1 and the hybrid radialene 2.
