Abstract: A series of well‐defined copper(I) complexes bearing ring‐expanded N‐heterocyclic carbene (NHC) ligands has been applied to the azide–alkyne cycloaddition reaction. The obtained results notably showed that the six‐membered NHC ligands outperform well‐established five‐membered ones. [CuI(Mes‐6)]… read more here.

DOI: 10.1016/j.cplett.2019.136704
Abstract: Abstract In this work, we design four multi-copper-mediated ring-expanded base pairs, which possess improved electromagnetic properties due to the introduction of cyclopentadienyl radicals and copper ions. These designed base pairs have smaller HOMO-LUMO gaps and… read more here.

Abstract: The structure-activity relationship of expanded-ring N-heterocyclic carbenes (NHCs) in the iron-catalysed Kumada aryl-aryl coupling reaction was explored. This was achieved by comparing the catalytic performance of Fe-NHC catalysts generated in situ containing NHCs that differ… read more here.

DOI: 10.3390/molecules26185464
Abstract: The review covers the chemistry of organoboron heterocycles structurally related to benzoxaboroles where one of the carbon atoms in a boracycle or a fused benzene ring is replaced by a heteroelement such as boron, silicon,… read more here.
