TLDR
The amalgame de cerium as discussed by the authors is a reactif efficace for the preparation chimioselective d'alcools homoally liques a partir d'halogenures allyliques and de composes carbonyles.Abstract:
L'amalgame de cerium est un reactif efficace pour la preparation chimioselective d'alcools homoallyliques a partir d'halogenures allyliques et de composes carbonyles. Ce meme reactif est utilise dans des reactions de type Reformatsky. Les reactifs organiques du Ce(III) generes par reaction d'organolithiens avec CeI 3 ou CeCl 3 sont moins basiques que les organolithiens et les reactifs de Grignard et reagissent avec divers composes carbonylesread more

Asymmetric Catalysis with Heterobimetallic Compounds
TL;DR: In this paper, the authors describe the development of rare-earth-alkali metal complexes such as LnM3tris(binaphthoxide) complexes (LnMB, Ln = rare earth metal, M = alkali metal), which are readily prepared from corresponding rare earth trichlorides or rare earth isopropoxides, and their application to catalytic asymmetric synthesis.

Metal‐Catalyzed Reductive Coupling Reactions of Organic Halides with Carbonyl‐Type Compounds
TL;DR: The recent findings in metal-catalyzed reductive coupling reactions of aryl halides and (pseudo)halides with carbonyl-type compounds are summarized, with particular emphasis on the mechanistic interpretation of the results and future aspects of this area of expertise.

Selective tin and zinc mediated allylations of carbonyl compounds in aqueous media
TL;DR: Aldehydes undergo preferential allylation in the presence of ketones by the tin or zinc mediated method, easily effected in aqueous media as discussed by the authors, and they can be easily allylated by a metal-oxide mixture.
