Convenient phosphorus tribromide induced syntheses of substituted 1-arylmethylnaphthalenes from 1-tetralone derivatives

A series of 1-arylmethylnaphthalenes 7a–g and 11 have been synthesized conveniently in good yields at room temperature through phosphorus tribromide induced aromatization of 1-aryl-[3,4]-dihydronaphthyl-methanols 6a–g and 10, which were obtained from 1-tetralone derivatives.
