Reaction between 1, 2-Epoxyoctane and Grignard Reagents

Reaction Between Grignard Reagents and Heterocyclic N-oxides Synthesis of Substituted Pyridines, Piperidines and Piperazines

Di-Grignard reagents and metallacycles

Aliphatic ,w-dibromides can be converted to the corresponding c,w-di—Grignard reagents; for those members carrying less than four carbon atoms between the functions, special procedures are required. The synthesis, structure and applications of the di-Grignard reagents are discussed; particular emphasis is placed on the structures of the corresponding cyclic dialkylmagnesiums, and on the use of ...

Thermal epimerization of diastereomeric Grignard reagents.

Thermal epimerization is the key to changing the endo-to-exo ratio of the diastereomeric bornyl and fenchyl Grignard reagents from 67:33 to 96:4 and from 20:80 to 80:20, respectively.

Enantioselective Addition of Grignard Reagents to Aldehydes

The addition of Grignard reagents to aldehydes in the presence of chiral aminoalcohols shows a moderate enantioselectivity. The study carried out with a series of ligands allows the correlation between the structural characteristics and their reactivity. Introduction The use of chiral aminoalcohol to lead asymmetrically nucleophilic additions of organometallics to carbonyl compounds is a field ...

Iron-catalyzed alkylations of aromatic grignard reagents.

Significance: The development of iron-catalyzed cross-coupling reactions is an extremely promising field of research, taken into account the importance of this method for current organic synthesis and the multiple problems connected with commonly used Pdand Ni-catalyzed processes. The group of Cahiez reported the first iron-catalyzed alkyl–aryl cross-coupling reaction, suitable for industrial l...
