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.
