4-Bromobenzo[1,2-d:4,5-d′]bis([1,2,3]thiadiazole)

Round 1

Reviewer 1 Report

The authors newly prepared and properly characterized 4-bromobenzo[1,2-d:4,5-d']bis([1,2,3]thiadiazole). The structure  was determined by elemental analysis, high resolution mass spectrometry, 1H, 13C NMR, IR and UV spectroscopy. For this reason, I recommend acceptance for publication in MolBank.

Author Response

The authors are grateful to the reviewer for a kind and highly professional review. There are no points to correct.

Reviewer 2 Report

In this contribution the authors describe the monobromation of benzo[1,2-d:4,5-d']bis([1,2,3]thiadiazole). This compounds was never isolated in the litterature and was obtained as nonseparable mixture of nonbrominated, monobrominated and dibrominated species. This building block has interestest for the developpment of material for optoelectronic. In this context this short not sounds well adapted for molbank. The compound is correctly characterized. I therefore recommend the publication of this paper after correction of few minor points.

1- Ref 1-3 should be completed by some other references that are not self-citations.

2- Regarding the bromination reaction: It is not clear what happened in case of entries 1-4: It the starting material fully recovered, or degradation is observed, or maybe dibromation? For entry 5: did you isolate other compounds than 1?

3- In synthetic experimentla part, Only the most important IR bands that can be attributed should be listed.

4- l 11 ...by bromination....

5 - l23 ...which has a stronger electron-withdrawing character

6- l 44 NBS  abbreviation should be defined

7- caption of figure S6: wavelength
