The Mechanism for Transition-Metal-Catalyzed Hydrochalcogenation of Unsaturated Organic Molecules,lassified by the initial behavior of precatalysts. In Type I mechanism, precatalyst M–X (M = Pd, Ni, Zr, Ln, and An) first undergoes protonolysis with REH (E = O, S, and Se) to generate active catalyst M–ER, which then undergoes insertion of alkyne into the M–ER bond (chalcogenometalation) to give 2

,Early Transition Metal (Group 3–5, Lanthanides and Actinides) and Main Group Metal (Group 1, 2, andpecially with respect to control of regio- and stereoselectivity and the synthesis of more complex nitrogen-containing skeletons. This article provides an overview over the application of catalyst systems based on the 17 rare earth elements, as well as group 4 and group 5 metals. These electropositi

Late Transition Metal-Catalyzed Hydroamination,ransition metal catalysis has been intensely developed in the hydroamination and additions of various kinds of amines to C–C multiple bonds have been achieved. The reaction pathways strongly depend on the choice of metal complexes, substrates, and reaction conditions. This chapter is organized prima

Chiral Metal Complex-Promoted Asymmetric Hydrophosphinations,on methodology which involves secondary phosphines as the nucleophiles. Chiral aza- and phosphapalladacycles are found to function as highly efficient templates or catalysts for the asymmetric P–H addition reaction. The versatile protocol allows for the asymmetric hydrophosphination of olefinic C=C

,Recent Progress in Transition Metal-Catalyzed Addition Reactions of H–P(O) Compounds with Unsaturataterials. Although classical synthetic methodologies are still used to synthesize them, the addition reactions of H–P(O) compounds such as .-phosphonates, .-phosphinates, and .-phosphine oxides have been developed to partially replace the classical methods and are envisioned to be an indispensable t

,Transition-Metal-Catalyzed S–H and Se–H Bonds Addition to Unsaturated Molecules,th thiols and selenols. In these reactions, the regio- and/or stereoselectivities of the addition products can be controlled by switching the transition metal catalysts. Metal sulfides and selenides (RE-ML., E = S, Se, M = Ni, Pd, Rh, Zr, Sm, etc.) play an important role as key catalyst species in t
