  • Bromination of naphthalene and derivatives: High temperature bromination XI
    作者:Arif Daştan、M. Nawaz Tahir、Dinçer Ülkü、Metin Balci
    DOI:10.1016/s0040-4020(99)00758-9
    日期:1999.10
    Thermal and photobromination of naphthalene and derivatives have been studied. Several hexabromo- (12, 13, 16 and 17), and tetrabromotetralin derivatives (23, 24, and 25) have been obtained as the major products, besides bromonaphthalene derivatives. Base-promoted elimination reactions of 12, 13, 16 and 17 provided di- (8) tri- (10) and tetrabromo-naphthalenes (22). A convenient method was developed

    Regio- and stereoselective synthesis are described for convenient preparation of hydroxy- and methoxynaphthalenes starting from naphthalene (\textbf1}). \textitcis,cis,trans}-2,3,5,8-Tetrabromo-4-methoxy-1,2,3,4-tetrahydronaphthalen-1-ol (\textbf6}), \textitcis,cis,trans}-2,3,5,8-tetrabromo-1,4-dimethoxy-1,2,3,4-tetrahydronaphthalene (\textbf7}), and \textitcis,cis,cis}-2,3,5,8-tetrabromo-1,4-dimethoxy-1,2,3,4-tetrahydronaphthalene (\textbf8}) were obtained with silver-induced substitution of \textittrans,cis,trans}-1,2,3,4, 5,8-hexabromo-1,2,3,4-tetrahydronaphthalene (\textbf3}). Base-promoted aromatization of dimethoxides \textbf7} and \textbf8} afforded 3,5,8-tribromo-1-methoxynaphthalene (\textbf9}) and 2,5,8-tribromo-1-methoxynaphthalene (\textbf10}). The reaction of \textbf6 }with sodium methoxide formed compounds \textbf10 }and 3,5,8-tribromonaphthalen-1-ol (\textbf16}). Bromination of \textbf9} and\textbf 16} with Br$_2}$ in dichloromethane at room temperature produced 2,3,5,8-tetrabromo-1-methoxynaphthalene (\textbf14}) and 2,3,4,5,8-pentabromonaphthalen-1-ol (\textbf18}), respectively, while compound \textbf10} did not react in the same conditions. Pyridine-induced elimination of hexabromide \textbf3} afforded 1,4,6\textbf-}tribromnaphthalene (\textbf21}) in 99\%} yield and thermolysis of the hexabromide \textbf3} gave mainly 1,4,6,7-tetrabromonaphthalene (\textbf22}). Tetrabromide \textbf22} was transformed to 1,4,6,7-tetramethoxynaphthalene (\textbf23}) by copper-assisted nucleophilic substitution reaction.
