The fully hydrolyzed organotin trihalides are the aggregated alkane- or arenestannoic acids [RSn(0)(0H)] . 

Reaction 14-1 can be used for making mono-, di-, or tri-alkoxides (n = 3, 2 or 1) (equations 14-7-14-9) though the reaction between organotin trihalides and sodium alkoxides is complete only when the reagents are heated together in benzene under reflux for some hours.2,3... 

Many additives have been investigated for promoting the direct reaction of organic halides with tin metal, but the reaction has limited use. Dimethyltin dichloride can be prepared from the reaction of methyl chloride with molten tin, but, in the laboratory, the reaction is used principally for preparing diallyl- or dibenzyl-tin dichlorides. The reaction between tin(ll) halides and organic halides to give organotin trihalides, similarly finds little practical application. 

Both trigonal bipyramidal, e.g. as in MeSnBr3-DMF, and octahedral complexes of organotin trihalides are known, e.g. fac- and / re/ -[ -PrSnCl3-(D]V[F)2] (30) have been...
