Tin ligands

It may be noted that, as expected, the equatorial distances are shorter than the axial. There is, of course, a close relationship between the square-pyramidal and the F-trigonalbipyramidal coordination sphere which are often difficult to discriminate when the tin-ligand bond distances in equatorial and axial positions do not differ significantly. 

Correlation between Tin-Ligand Distances and Coordination Numbers... 

In Section 3.2.1 we have deduced the dependence of the geometries of tin-ligand arrangements on the coordination number. We will now study the distances between the tin(II) atom and the ligand when the coordination number is changed. In Tables 8-11 the mean distances between the central tin atom and four different ligands (N, O, F and S) are listed. As expected, these distances increase with rising... 

A typrcal C—P—C bond angle m a PMc, complex is 102 . but the cone angle lor tins ligand is given as 118 in Table 15 10. Explain. 

Acetoxylation of toluene using a Pd(OAc)2-Sn(OAc)2-charcoal catalyst selectively produces benzyl acetate with high turnover numbers ( 100).373,434 The active catalyst presumably contains Pd—Sn bonds. Tin ligands are known to increase the 7r-acceptor ability of palladium, and may favor the coordination of the toluene in the form of a benzylic 7r-allyl complex (141) which is nucleophilically attacked by the acetate anion.435... 

The results for the tin-containing complexes (41, 42) also permit the examination of the relationship between /pt-p trans to the tin ligand and the indirect coupling constant 2J p-pt-sn- There are accurate linear relationships for two series of complexes (see Figure 13) that...
