In a recent article published in Green Chemistry, Wei Han and coworkers report the following protocol for the synthesis of biaryl ketones via carbonylative Suzuki-Miyaura coupling.

This protocol is green in several aspects. Which of the following IS NOT true about the greenness of this reaction?

a) Expensive and less abundant palladium-based catalysts are replaced with inexpensive FeCl₂.

B) The use of chloroform as a carbon monoxide source eliminates the need to work with high pressures of toxic, flammable carbon monoxide.

C) The reaction utilizes a greener solvent alternative – PEG-400

D) The reaction has high atom economy.

E) High selectivity is achieved for the carbonylative coupling product (the biaryl ketone) over the non-carbonylative coupling product (the biaryl)

Which of the following general reactions has the highest (intrinsic) atom economy

(hint: % A.E. = M.W.(desired product) ÷ M.W.(all reactants))?

A) Wittig reaction

B) Diels-Alder reaction

c) Suzuki-Miyaura cross-coupling reaction
