Transition-metal—tin bonds

Figure 10.9 Some examples of metal sequences and metal clusters containing tin-transitional metal bonds.

Table 19-5 Compounds with a tin-transition metal bond.

A number of organotin compounds with a tin-transition-metal bond have been examined this bond has usually been to iron to facilitate study... 

Many transitional metals have now been incorporated into compounds containing tin-transitional metal bonds io. 28s. xhe syntheses can be roughly divided into four main classes. 

The number of individual compounds that possess one or more tin-transitional metal bonds is very large, and the table only includes some representative examples. 

A number of reagents cause fission of the tin-transitional metal bond so. 29t.

The structural aspects of tin-transition metal complexes are well studied. Some recent examples of metal-tin single and double bonded complexes are provided in Tables 11 and 12. 

Although the tin hydride + alkyl halide method is probably the most important way of making alkyl radicals, we should mention some other methods that are useful. We said at the beginning of the chapter that carbon-metal bonds, particularly carbon-transition metal bonds, are weak and can homolyse to form radicals. Alkyl mercuries are useful sources of alkyl radicals for this reason. They can be made by a number of routes, for example, from Grignard reagents by transmetailation. 

This part concludes the description of the formation of carbon bonds to transition-and inner transition-metal bonds which is then followed by the formation of silicon, germanium, tin, and lead bonds to these metals.
