Silicon-Carbon Bond Cleavage from a Hydroboration Sequence

Key Points

• The research investigates the unexpected silicon-carbon bond cleavage from hydroboration sequences using specific reagents.
• Utilized bis(1-methyl-ortho-carboranyl)borane as a hydroboration reagent.
• Conducted reactions with internal pyridyl/trialkylsilyl alkynes.
• Analyzed bond cleavage outcomes under mild reaction conditions.
• Observed unanticipated Si-C bond cleavage following selective 1,1-hydroboration.
• Identified the rare rupture of the Si-Me bond under the experimental conditions.
