An efficient and practical method for the synthesis of naphthalene derivatives via Fe(III)-catalyzed benzannulation of 2-(2-ozoethyl)-benzaldehydes and alkynes has been developed. The system holds the advantages of cheap catalysts, wide substrate scope, and mild reaction conditions.
Synthesis and Photophysical Properties of 9,10-Bis(3-aryl-2-naphthyl)anthracenes
The 9,10-bis(3-aryl-2-naphthyl)anthracenes 3 were prepared by the benzannulation reaction of 2-(phenylethynyl)benzaldehyde (1) and the corresponding 9,10-bis(arylethynyl)anthracenes 2 in the presen...
