Hydrogenation and Related Reactions

This chapter describes the application of P-stereogenic ligands in transition metal-catalysed hydrogenation and related reactions. The main section of the chapter deals with Rh-catalysed hydrogenation of functionalised olefins and carbonyl compounds. It includes a classification of the typical substrates, the description of the best results of each family of substrates and a discussion on the mechanism of the reaction. The next section describes some Ru-, Ir- and Pd- catalysed hydrogenations of alkenes, ketones and imines. The final sections describe hydrosilylation and hydrogen transfer, which also reduce double bonds but without using hydrogen gas.
