Interpretation Introduction
Interpretation:
Products formed in the Stille coupling reactions for given compounds are to be determined.
Concept introduction:
Stille coupling is a reaction in which organotin compounds are coupled with organic halides. Here, organotin compounds are used as coupling agents.
Stille coupling is a carbon–carbon bond formation reaction between aryl halide and organotin compound.
The Stille coupling reaction takes place in presence of palladium catalysts. This reaction is commonly used for
