Stannole is an organotin compound with the formula (CH)4SnH2. It is classified as a metallole, i.e. an unsaturated five-membered ring containing a heteroatom. It is a structural analog of pyrrole, with tin replacing the nitrogen. Substituted derivatives, which have been synthesized, are also called stannoles.[1]
Examples
1,1-Dibutylstannole is a pale yellow oil prepared from 1,4-dilithio-1,3-butadiene and dibutyltin dichloride [2]
Reactions
1,1-Dimethyl-2,3,4,5-tetraphenyl-1H-stannole, for example, can be formed by the reaction of 1,4-dilithio-1,2,3,4-tetraphenyl-1,3-butadiene and dimethyltin dichloride.[3] 1,1-Disubstituted stannoles can be formed in the [2+2+1] cycloaddition reaction of two acetylene molecules with an organotin molecule SnR2.[4]
