Diphenyl Carbonate: Recent Progress on Its Catalytic Synthesis by Transesterification

Round 1

Reviewer 1 Report

The review entitled "Diphenyl Carbonate: Recent Progress on its Catalytic Synthesis by Transesterification" well describes the state of art on the production  of diphenyl carbonate, an important starting material for polycarbonates polymers. I believe the manuscript is complete and suitable for publication in the Section "Industrial Catalysis". However, there are few issues that shoud be considered before publication:

1- At no point is the meaning of the acronyms MPC and DPC mentioned, I believe it is monophenylcarbonate and diphenylcarbonate, but it would be appropriate to mention it in the text

2- I suggest that all the Tables in the support informations should be presented as part of the manuscript, and not only as a appendix;

3- About the selectivity, could the authors explain, how is it calculate? I was not able to understand how could a process had 100% selectivity, but the MPC and DPC yields were, 7,6% and 14,4%, respectively (Example of Table S5, entry 1). Does the selectivity value refers to the sum of both (MPC and DPC)? should not it be used for one specific product?

4-Figure 7 shows the mechanism of molibdenium catalyst, however it should refers to tin catalyst....Figure 7 is equal to Figure 9...

Reviewer 2 Report

In this work, the authors examined Diphenyl Carbonate: Recent Progress on its Catalytic Synthesis by Transesterification. The topic is interesting, but with issues mentioned below, authors should revise for publication at current level.

1.      The manuscript is not formatted properly that need to be revised. For example, tables should be three-line tables; blank space is needed between number and unit. reference style is not uniform.

2.      In paragraph 1 of section “Thermodynamic analysis of transesterification”, the logic was confusion. The authors should introduce briefly existing methods of Thermodynamic analysis of transesterification mentioned at the beginning first, then focus on comparative study.

3.      Case study was not enough, add more examples

4.      Add latest references.

Reviewer 3 Report

The review by Shi and co-workers discussed the catalytic synthesis of diphenyl carborane using transesterification. The review covered a diverse array of catalytic processes under both heterogeneous and homogeneous conditions, with insights into mechanistic aspects offering a comprehensive summary of the literature. Though plenty of other reviews are available on diphenyl carborane, none have focused on transesterification previously. Therefore, I recommend publication in Catalysts once the following points have been addressed:

1. The quality of the ChemDraw figures is not up to the mark. The authors should use the widely accepted ChemDraw template and refine all the figures to improve aesthetics. Additionally, ensure consistency in color combinations throughout.

2. The reaction pathways for transesterification could be consolidated into a single scheme.

3. Figure 1: Compound I should be depicted as a double bond, and the bond angle of phenol needs adjustment. Intermediate II requires redrawing.

4. Figure 2: Structures a and b require attention.

5. Figure 11: The structures are missing double bonds.

6. Ensure all references are appropriately cited according to the journal norms.

7. In Table 3, subscripts should be used for digits in the catalysts, and consistency is needed in reporting yields to either one or two decimal points.

8. When denoting temperature, ensure a space separates the digit and the degree Celsius symbol for consistency.

9. Figure 8: The mode of activation is unclear. Providing clarification in the text would enhance reader understanding. Please replace the half arrows with full ones for clarity.

10. Several publications are missing from the discussion and references, such as "Chin J Catal, 2006, 27, 7" and "Applied Catalysis A: General, 2004, 260, 19," among others.
