Two adamantane-bridged tripodal trisimidazolium or trisbenzimidazolium salts were designed as C-3v-symmetrical tricarbene ligands and synthesized in good yields. The reaction of the tripodal trisazolium salt precursors with silver oxide provided t...

Chiral bis(imidazolidine)-derived NCN-rhodium complexes ([PhBidine-RhX2] and [tBu-PhBidine-RhX2]) were prepared by a CH insertion method, and the structures were unequivocally determined by X-ray crystallographic analysis. The [tBu-PhBidine-Rh(OAc...
