Organomagnesium amides structure

The structures in the solid state of three of the initially formed organomagnesium amides, 222, 223 and 224, were determined by X-ray crystallography. All three compounds are discrete monomers and have comparable structures of which that of 222 is shown (Figure 93). In 222 the ethyl group is a-bonded to magnesium and interacts with the three nitrogen atoms of the A-alkylated 2,6-bis(imino)pyridine in a pincer-type ... 

This chapter is devoted to the chemistry of organomagnesium-group 15- and group 16-bonded complexes, with emphasis on their synthesis, structural characterization and utility. In particular, organomagnesium amides will be the central focus of the first section, as...

Detailed reviews on the structures of organomagnesium compounds and the constitution of their solutions have been published [D, 1, 2]. These references, especially the first two, also cover alkylmagnesium hydrides, amides, alkoxides and thiolates. However, while all of these compounds are of intrinsic interest, they are little used in synthesis.
