N-Bromosuccinimide can be used as a reagent: In the Wohl-Ziegler reaction (bromination at allylic positions via a radical pathway). To synthesize benzils and aliphatic 1,2-diketones from hydrobenzoins and 1,2-diols in the presence of CCl4 as a solvent. ...
Furthermore, the developed protocol provides an efficient and straightforward method for the preparation of deuterated (methylsulfinyl)methyl esters by use of deuterium-labelled DMSO as the reagent.Ya WuMengsha ZhangYanli ZhangMingyang LiWeisheng Feng...
NBS is an inexpensive, commercially available, and versatile reagent. This reagent has recently been used as an effective catalyst for the acetalization of carbonyl compounds, the conversion of aldehydes to 1,1-diacetates, and the acylation of alcohols under mild and nearly neutral reaction conditio...
