Interpretation Introduction

Interpretation:

The coupling reaction and the staring material to form the given product has to be identified.

Concept Introduction:

Stille coupling uses a tin reagent (${\text{Bu}}_{\text{3}}\text{Sn-R}$) in which the R-group is commonly a vinyl species with alkenyl, aryl or alkenyl halide with palladium to give a new C-C bond.

Stille coupling gives conjugated dienes or alkenyl aryl system.
