Chapter 19, Problem 19.9YT

Interpretation Introduction

Interpretation:

Whether Suzuki reaction or Heck reaction should be used to produce the single bond between the two phenyl rings in biphenyl, C6H5iC6H5, is to be determined. Also, what would the precursors is to be determined.

Concept introduction:

There are several variations of the Suzuki reaction, but in the general reaction, a vinylic or aryl halide is treated with an organoboron compound and a palladium catalyst (PdLn) under basic conditions. Suzuki reactions involving possible E/Z isomerism usually proceed with retention of configuration. Similar to the Suzuki reaction, the Heck reaction can couple one vinylic or aryl group to another.
