Abstract: Bis(triphenylsilyl) and dibenzyl ytterbium(ii) complexes supported by the macrocyclic polyamine ligand Me4TACD (1,4,7,10-tetramethyl-1,4,7,10-tetraazacyclododecane) reacted with H2 to give the cationic ytterbium hydrides [(Me4TACD)2Yb2(μ2-H)(2+n)](2-n)+ (n = 0, 1). The hydrides catalyzed the H2/D2 isotope exchange as… read more here.

Abstract: Treatment of a divalent ytterbium hydride complex [(TpAd,iPr)Yb(H)(THF)] (TpAd,iPr = hydrotris(3-adamantyl-5-isopropyl-pyrazolyl)borate) (1) with CO, CO2 and CS2 resulted in the formation of a divalent ytterbium ethenediolate complex [(TpAd,iPr)Yb]2(cis-OCHCHO) (2), a formate complex [(TpAd,iPr)Yb(κ2-O2CH)(THF)] (3), and… read more here.
