 Title    Abbau von Induktionsperioden und Steigerung der Aktivität homogener Hydrierungskatalysatoren mit Iridium als Zentralatom Reduction of Induction Periods and Increase of Activity of Homogenous Iridium Hydrogenation Catalysts  
 Abstract    With complexes of iridium as catalysts, induction periods are typical for homogeneous hydrogenation of olefins in bulk. The induction period decreases, as a rule with increasing activity, at higher temperatures and may be suppressed with dibenzoylperoxide, azo-bisisobutyrodinitrile, tetrachloro-l,4-benzoquinone or by preactivation. Triethylamin and SnCl2 • 2H2O are unsuitable additives. The operation "preactivation" leads additionally to great substrate/catalyst-turnover numbers.
