摘要

We previously showed that 2,4,4,6-tetrabromo-2,5- cyclohexadienone in the presence of triphenylphos- phine is an efficient and mild reagent replacing the hydroxy group by bromine in alcohols [1, 2] and carboxylic acids [2]. The goal of the present work was to examine reactions of the system 2,4,4,6-tetra- bromo-2,5-cyclohexadienone3triphenylphosphine (I) with aliphatic and aromatic carbonyl compounds. As model reaction we chose that between complex I ...
