- Title
One-Pot Synthesis of Butadiyne-Bridged Bipyrrole Derivatives and Bisporphyrin.

- Abstract
Butadiyne-bridged bipyrroles were prepared from 2-iodopyrroles and trimethylsilylacetylene through a facile onepot synthesis involving a modified Sonogashira coupling reaction and in situ aerobic oxidative coupling of the acetylenic pyrroles; the products were obtained in yields of 31-72 % depending on the substituents on the pyrrole. The acetylenebridged diacids obtained from the hydrolysis of the corresponding ester derivatives are highly stable, unlike most reported oligopyrrolic diacids. This protocol could be easily extended towards the synthesis of butadiyne-bridged bisporphyrins.
