Halostannanes synthesis

Another major route for synthesis of stannanes is reaction of an organometallic reagent with a trisubstituted halostannane, which is the normal route for the preparation of aryl stannanes. 

In conclusion it should be noted that organometallic synthetic methods of organyl-halostannanes were not as widely used as in the synthesis of the isostructural compounds of silicon and germanium. Section III.E explains the reason for this. 

Reactions of halostannanes with complex hydrides provide routes to stannanes (Table 1). Complex hydrides most used are MBH. (M = Li, Na, K) and LiAlH. The LiBH and LiAlH, reductions are carried out in aprotic ether solvents (THE, EtjO, monoglyme). Sodium and K hydroborate reactions may be carried out in H O. Most complex hydride reductions are adaptable to Sn — D bond synthesis (see also 1.6.7.1.4). Halostannanes are reduced by LiAlH ...
