A facile one-potsynthesis of butadiyne bridged bipyrroles could be achieved from 2-iodopyrroles and trimethylsilylacetylene via a modified Sonogashira coupling and in-situ aerial oxidative coupling of the acetylenic pyrroles in 31-72% yields, depending upon the substituents on pyrrole. The acetylene bridged diacids obtained from hydrolysis of the corresponding ester derivatives were highly stable
An antiparallel double-strand of a BODIPY–zinc–porphyrin dyad was assembled via geometrical complementarity of an unusual B–F⋯Zn coordination bonding interaction.
