Phenanthrene is an important structural motif in chem. and materials science, and many synthetic routes have been developed to construct its skeleton. However, synthesis of unsym. phenanthrenes remains a challenge. Here, an efficient one-pot tandem reaction for the preparation of phenanthrenes via sequential γ-C(sp2)-H arylation, cationic cyclization, dehydration, and 1,2-migration was developed. A wide range of sym. and unsym. phenanthrenes with diversified functional groups were synthesized with good to excellent yields. In the experiment, the researchers used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5SDS of cas: 31938-07-5)
2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5) has been used in the synthesis of a series of aminoethylbiphenyls, novel 5-HT7 receptor ligands or 2-(1-cyano-1-(3-bromophenyl))methylidene-3-phenylthiazolidine-4,5-dione.SDS of cas: 31938-07-5
