“…In addition, we deemed that reduction of a carbon-donor ligand, such as CO, may provide a successful synthetic route to a heteroatom-containing cobalt carbyne. This strategy has been employed by Peters and co-workers for the generation of terminal carbynes of iron. , However, to prevent cluster formation by carbyne-coupling and related processes, we focused on the reduction of an encumbered organoisocyanide ligand (isolobal to CO) in order to sterically shield a [Cp*Co≡C] unit from intermolecular aggregation. Accordingly, we report here the synthesis, characterization and reactivity of a dianionic cobalt terminal carbyne derived from the m -terphenyl isocyanide CNAr Tripp2 (Ar Tripp2 = 2,6-(2,4,6-( i -Pr) 3 C 6 H 2 ) 2 (C 6 H 3 ) .…”
