1,1-Distannyl-1-alkenes of the type RR′C=C(SnMe3)2 can be readily prepared from (trimethylstannyl)lithium and geminal dibromoalkenes. An extension of this method to include the preparation of vicinal distannylalkenes is in general not possible. Hydrostannation of the geminal distannylalkenes gives tristannylalkanes; bromodestannylation using N-bromosuccinimide occurs readily, as does halodemethylation at tin using dimethyltin dihalides. Palladium-catalyzed coupling reactions between geminal distannylalkenes and organic halides are possible, but stereoselective monocoupling is probably not realizable. Selected multinuclear NMR data for the compounds prepared are presented.
