Triorganotin hahdes—

Diorganotin dihalides react differently, since they produce polytin disodium compounds75-77, which consequently can be treated with triorganotin hahdes ... 

Various tin-tin bonded compounds are known. The simplest tin tin bonded compounds, hexaorganoditins, RsSnSnRs, are available by several routes, including (i) from triorganotin halides and alkali metals in ether or liquid ammonia (equation 65) (ii) from triorganotin hahdes and triorganotin lithium compounds (equation 66) and (iii) from triorganotin hydrides in the presence of a base (such as pyridine) or on reaction with Sn-O, Sn-N, or Sn-S species (Scheme 14). 

Preparation ndMa.nufa.cture. Monoorganotin haHdes are the basic raw materials for all other triorganotin compounds and are generally prepared by Kocheshkov redistribution from the tetraorganotin, eg, tetrabutyltin or the higher organotin haHdes ...
