Reactions involving tris(trimethylsilyl)silane and triflic acid are particularly interesting in organic chemistry. Here are a few notable examples:

1. Hydrosilylation Reactions: Tris(trimethylsilyl)silane, often referred to as TTMSS, is used as an alternative to tin hydrides in radical reactions. When used with triflic acid, it can promote the reduction of alkenes and alkynes into their respective alkanes.

2. Deoxygenative Transformations: One significant application involves the deoxygenative transformation of ketones into alkenes. This reaction is facilitated by the cooperative action of TTMSS and triflic acid, which generates carbocations that subsequently eliminate to form alkenes.

3. Cleavage of Si-Si Bonds: The combination of TTMSS with strong acids like triflic acid can result in the cleavage of silicon-silicon bonds. This reaction forms siloxane derivatives along with the evolution of hydrogen gas.

4. Reduction of Aldehydes and Ketones: Tris(trimethylsilyl)silane and triflic acid can also be used in the reduction of aldehydes and ketones to form the corresponding alcohols or ethers, depending on the reaction conditions and the presence of additional reagents.

5. Aldol Reactions: Although not directly involving TTMSS and triflic acid together, it's interesting to note that the aldol reaction can be catalyzed by bis(trifluoromethane)sulfonimide, which is somewhat related to triflic acid in its superacid properties.
