Dimethyltin dichloride diorganotin compounds

Physica.1 Properties. Physical properties of some typical diorganotin compounds are shown in Table 6. The diorganotin chlorides, bromides, and iodides are soluble in many organic solvents and, except for dimethyltin dichloride, are insoluble in water. 

In one case a discrete polymer, dodecamethylcyclohexatin, has been obtained 211) from the reaction of dimethyltin dichloride with sodium in liquid ammonia. Using diorganotin dichlorides and sodium in xylene, a,co-dichloropolytin compounds may be obtained in yields of up to 50% 212). One major product was obtained from each tin halide dimethyltin dichloride produced a ditin diethyl-, dipropyl-, and dibutyltin dichloride gave tetratin, tritin, and pentatin, respectively 212).
