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)2Yb22-H)(2+n)](2?n)+ (n = 0, 1). The hydrides catalyzed the H2/D2 isotope exchange as well as hydrogenation and hydrosilylation of 1-hexene.
