Abstract:

Green synthesis of α-biphenyldicarboxylate(α-DDB) is an exploratory experiment for secondyear undergraduates. The α-DDB is synthesized by using gallic acid as the starting material. Two safe and low toxic reagents, dimethyl carbonate(DMC) and 1,3-dibromo-5,5-dimethylhydantoin(DBDMH) were used to replace extremely toxic dimethyl sulfate(DMS) and strongly corrosive and toxic bromine, respectively. The feasibilty of green chemical synthesis of α-DDB has been explored and realized in laboratory teaching.

Key words: α-DDB, DMC, DBDMH, Green chemistry
