I don't have the Chem Lett reference, but it is not that hard to acquire.
If you would have read the Addendum during correction
from the Synthesis article, you would have found an equally interesting sodium percarbonate (SPC) / sodium perborate (SPB) review:
A McKillop, W R Sanderson. Sodium perborate and sodium percarbonate: cheap, safe and versatile oxidising agents for organic synthesis. Tetrahedron 51(22) (1995) 6145-6166. DOI:
This review is complementary to the one published in Synthesis, and for sure is a must-read as well.
My interest was usually in SPB, and not SPC, because it was easier to get this compound in smaller quantities. I was unable to locate a company which wanted to deliver me less than 1 m3
SPC, or didn't make a 100x profit on the substane.Useful SPB references in my collection:
1. Alexander McKillop, J A Tarbin. Functional group oxidation using sodium perborate. Tetrahedron 43(
(1987) 1753-1758. DOI:
- Sodium perborate in acetic acid is an effective reagent for the oxidation of anilines to nitroarenes and of sulphides to either sulphoxides or sulphones. it is also an excellent reagent for the oxidative deprotection of ketone dimethylhydrazones. Baeyer-Villiger oxidation of ketones can be carried out with sodium perborate in either trifluoroacetic acid or acetic acid/trifluoroacetic acid mixtures, and hydroquinones and certain highly substituted phenols are smoothly converted into quinones.
2. Alexander McKillop, Duncan Kemp. Further functional group oxidations using sodium perborate. Tetrahedron 45(11) (1989) 3299-3306. DOI:
- Sodium perborate in acetic acid is an effective reagent for the oxidation of aromatic aldehydes to carboxylic acids, iodoarenes to (diacetoxyiodo)arenes, azines to N-oxides, and various types of sulphur heterocycles to S,S-dioxides. Nitriles are unaffected by the reagent in acetic acid, but undergo smooth dehydration to amides when aqueous methanol is employed as solvent.

- Sodium perborate in acetic acid at 95°C oxidizes aromatic aldehydes, ?-hydroxycarboxylic acids, 1,2-diketones, benzoin, 1,2-diols and some unsaturated compounds.

- The selective monobromination of various deactivated anilines using potassium bromide and sodium perborate as oxidant has been achieved. The use of ammonium molybdate as catalyst accelerates the rate of reaction but is not essential to obtain good yields and high selectivities.
7. G W Kabalka, K Yang, N K Reddy, C Narayana. Bromination of alkenes using a mixture of sodium bromide and sodium perborate. Synthetic Communications 28(5) (1998) 925-929.Abstract
- Bromination of alkenes with sodium bromide in the presence sodium perborate provides a simple, high yield route to dibromoalkanes.
8. B P Bandgar, Miss Neeta J Nigal. Regioselective catalytic halogenation of aromatic substrates. Synthetic Communications 28(17) (1998) 3225-3229.Abstract
- Regioselective chlorination and bromination of some aromatic substances have been carried out using KCl and KBr in presence of sodium perborate as an oxidant and sodium metavanadate, sodium tungstate, ammonium metavanadate and ammonium molybdate as efficient catalysts. This environmentally friendly catalytic halogenation method gave good yields of products under mild conditions.
Except for the McKillop review and the imine>formamide rearrangement article, all articles can be req'd.
Some notes: The Kabalka article can be applied on propenylbenzenes to yield their dibromo derivatives (tested in the lab). I tried a iodination as well, but the end product was not purified nor analysed. However, upon addition of KI to the acetic acid/SPB mixture, there was an immediate formation of I2 (colour) and heat.
The Xie article has been evaluated a loooong time ago (before I found this board) and seems to work as well. I used Ac2O as reactant/solvent though, so I don't know how many bees are waiting for this adaptations. Reaction was over very quickly though. The method is solvent sensitive. DCM, for instance, has been tested and failed. Usually, acetic acid or acetic anhydride (or trifluoro analogues) are involved.
