Industrial Aspects of Selectivity Applying Homogeneous Catalysis,mplies that search for selectivity provides a great challenge to the chemical industry necessitating substantial research and development efforts. In aiming at selectivity, catalysis plays an important role. In the last decades, homogeneous transition metal based catalysts have emerged as especially promising in obtaining selectivity.

Palladium Catalyzed Reduction of Aryl Sulfonates. Selectivity Control and Application to Anthracyclanthracyclines these molecules consist of an aglycone moiety and an aminosugar joined through a glycosidic bond at C-7; the two structures differ only at C-14 where daunorubicin bears a methyl group and doxorubicin an hydroxymethyl moiety (Figure 1).

Catalytic Carbonylations of Nitrogen Containing Organic Compounds,1]. On the other hand different routes to the metal promoted C-N bond formation lead to a different type of products. These catalytic syntheses involve the interaction of carbon monoxide with organic azides, RN. , with aromatic nitro compounds, ArNO. , and with amines in the presence of molecular oxygen (Scheme 1).

The Design of a Chemoselective Reduction Catalyst, obtained in α, β -unsaturated ketones, where the olefinic double bond is invariably affected. Only recently has this reaction been reported to be promoted by Cp.ZrH. and Cp.HfH., to give selective carbonyl group reduction in hydrogen transfer reaction using propan-2-ol as source of hydrogen .
