The reaction of the isolable disilyne 1 , RSi&z.tbd;SiR (R = Si i Pr[CH(SiMe 3 ) 2 ]), with MeLi produced the methyl-substituted disilenyllithium 2 as the primary product. However, 2 is not thermally stable at room temperature in THF, and slowly isomerized to the unexpected disilacyclopropylsily...
