In this study, anthracenes were efficiently synthesized from o-alkynyldiarylmethane using a novel method that exploits the synergistic effect between Bi(OTf)3 as the catalyst, and trifluoroacetic acid (TFA). Through this reaction, we achieved the rapid and efficient synthesis of anthracenes bearing various functional groups under mild conditions.

A concise gold-catalyzed method for the preparation of anthracenes from o-alkynyldiarylmethanes has been developed. Under mild reaction conditions, versatile anthracene derivatives were formed in moderate to good yields. The high flexibility, broad substrate scope, and mild nature of this reaction render it a viable alternative for the synthesis of anthracenes.

Golden tendencies: The title reaction for synthesizing cyclopentenone derivatives utilizes a gold complex and 8-methylquinoline oxide as the catalyst system (see scheme; IPr=1,3-bis(diisopropylphenyl)imidazol-2-ylidene). Such products are not attainable using diazocarbonyl reagents, as the gold carbenoids tend to react with C-H bonds. Copyright
