| 1,4-dibromonaphthalene Usage And Synthesis |
| Chemical Properties | light orange-beige fine crystalline powder | | Uses | 1,4-Dibromonaphthalene is used in the annelation of PAHs. Also used in the synthesis of novel, orally active dual NK1/NK2 antagonists. | | Application | 1,4-Dibromonaphthalene is mainly used for pharmaceutical intermediates. synthesis of tribromo methoxynaphthalenes from 1,4-dibromonaphthalene. starting material 1,4-dibromonaphthalene was prepared starting from naphthalene or 1-bromonaphthalene.5,8-Dibromo-1,4-naphthoquinone and 5,8-diiodo-1,4-naphthoquinone were prepared from 1,4-dibromonaphthalene and 1,4-diiodonaphthalene. | | Preparation | An environment-friendly method was developed to synthesize 1,4-dibromonaphthalene (1,4-DBN) using 1,3-dialkylimidazolium and pyridinium ionic liquids as catalysts, over which the yields of 1,4-DBN were obtained as high as 100%.An environment-friendly method for synthesis of 1,4-dibromo-naphthalene in aqueous solution of ionic liquids |
