2-(4-(Fluorosulfonyloxy)phenyl)benzoxazole

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this short note, Khlebnikov and coworkers describe the synthesis and emission properties of 2-(4-(Fluorosulfonyloxy)phenyl)benzoxazole. The authors claim that the fluorosulfate group could be used for the immobilization of the compound on materials surface. In state the charzcterization of the compound are incomplete. If extra experiment are performed I would be pleased to support the puplication of this paper.

 

1- p2 the following sentence is confusing "Thus, using SuFEx reaction for obtaining benzoxazole derivatives could increase their biological activities."In fact the SuFEx reaction is used to functionalize the benzoxalole fragment, this is not to forn a benzoxazole fragment.

2- Schemes 1&2: please add yield of each reaction.

3- SDI acronym sghould be defined at 1st use in manuscript.

4- THe photophysical characterization should contain absorption spectrum and molar absorption values, photoluminescence quantum yield, Stokes shifts at least. The theoretical absoprtion spectrum should be also calculated.

5- for 1H nmr description, relative integration should be systematically provided.

6- 13C nmr chemicla shifs should be provided with only one decimal.

7- Title compound and intermediate should be characterized by either elemental analyses for CHN (other atoms may be included) in the form of e.g. 'Found: C, 78.3; H, 6.7; N, 14.3%; 'molecular formula CxHyNzOwS' requires C, 78.4; H, 6.9; N, 14.7%' or HRMS e.g. 'Found: [M+H]+ 234.5678; 'molecular formula CxHyNzOwS' requires [M+H]+ 234.5690. Note: For elemental analyses, accuracy to within ±0.4 % is expected, and for mass spectral data used for identification, exact masses, quoted to four decimal places, should be accurate to within 5 ppm.

Comments and Suggestions for Authors

Even fit he authors did not measure photoluminescence quantum yield, they have adressed all other points I raised. The manuscript is now publishable.

p5 l5 "The GC-MS data, NMR and UV spectra of compounds 2.." should be "The GC-MS data, NMR and UV spectra of compound 2.."
