Dialkyltin dihalides

An interesting example is the electrolysis of alkyl halides on tin anodes and platinum cathodes which yields dialkyltin dihalides. The current yield is extremely high, Ca 5 g... 

The use of a sodium-tin alloy for the preparation of tetramethyltin preceded use of the corresponding sodium-lead alloy (64,66), but was subsequently displaced by other methods. Currently, the Direct Reaction is used to prepare dialkyltin dihalides, and generally requires an oxygen-containing solvent plus another metal as accelerator (66) ... 

The 119Sn NMR spectra show that a similar exchange takes place between dialkyltin dimethoxides and dialkyltin dihalides the principal species present in solution is the alkoxide halide 14-4, which at high concentration forms the dimer 14-5, which can be isolated as a crystalline solid.39... 

Various allyl-, benzyl-, and alkyltin halides have been prepared by direct methods compounds have included functionally substituted dialkyltin dihalides X2Sn[(CH2) Y]2 (k = 1 or 2, Y = R2NCO, ROCO, RCO n = 2, Y = NC = 3,Y = R0). 

Polymeric organotin arsonates, 64, are formed from the reaction of dialkyltin dihalides and disodium salts of organoarsonic acids or similarity by reaction with silver arsenate. " This was one of the first papers by Nobel-winner Alan MacDiarmid. 

No compounds of this structure have been reported in the older literature, though there is only a formal difference between a dialkyl(dialkyltriazeno)tin halide reported in this chapter to dialkyl(bipyridino)tin dihalide listed in Chapter as addition compound of dialkyltin dihalide. The compounds list-...
