We have synthesized a new type of metallaaromatic complexes, namely the hydride-β-iridanaphthalenes TpMe2tiebar above startr(H)[C(CH2R′)-C6H4-o-C(R)═tiebar above endC(R)] (benzo-3-H,CH2R′), by reaction of the benzo-iridacyclopentadiene TpMe2tiebar above startr[C6H4-o-C(R)═tiebar above endC(R)](OH2) (benzo-1-OH2) (TpMe2 =...

The fully CO2Me substituted aquo-iridacyclopentadiene 1 reacts with a variety of aromatic aldehydes, at 90–120 °C, with the formation of bicyclic Fischer-type carbenes, generated by the transfer of the aldehydic H atom to an α carbon of the metallacycle and concomitant bonding of the O atom to the adjacent β carbon. These carbenes have a...

Cationic rhodium(I) complexes containing picolyl-NHC (NHC = N-heterocyclic carbene) ligands that differ in the substitution at the 6-position of the pyridine donor serve as efficient E-selective alkyne hydrosilylation catalyst precursors. Particularly, when the steric hindrance of the picolyl fragment is increased, a catalyst...

A series of Ru complexes containing lutidine‐derived pincer CNC ligands have been prepared by transmetalation with the corresponding silver‐carbene derivatives. Characterization of these derivatives shows both mer and fac coordination of the CNC ligands depending on the wingtips of the N‐heterocyclic carbene fragments. In the presence of tBuOK,...

Reduction of nitrous oxide (N2O) with H2 to N2 and water is an attractive process for the decomposition of this greenhouse gas to environmentally benign species. Herein, a series of iridium complexes based on proton-responsive pincer ligands (1−4) are shown to catalyze the hydrogenation of N2O under mild conditions (2 bar H2/N2O (1:1), 30 °C)....
