and easily available, stable starting materials were used, resulting in a concise and highly efficientroute for the synthesis of the title compounds. This novel pseudo five-component synthesis starting from iodo(hetero)arenes is particularly suitable as a direct access to well-defined thiophene oligomers, which are of peculiar interest in materials science.

The generation of permeable porous-cage nanospaces in solution by a highly charged cationic [Pd6(RuL3)8]28+ cage for multirole and multi-way supramolecular catalysis is reported.
A highly efficient cobalt-catalyzed homocoupling of terminal alkynes with di-tert-butyldiaziridinone as the oxidant has been developed. The protocol tolerates a wide array of terminal alkynes, both activated and unactivated alkynes, to afford the corresponding conjugated 1,3-diynes. The mild reaction conditions further allow late-stage homocoupling of alkynes derived from complex natural products.
