1-broMo-4-phthaldehyde Chemical Properties,Usage,Production
Uses
4-Bromo-1-napthaldehyde is used in the synthesis and antimicrobial activity of chalcones and flavones.
Synthesis
79996-99-9
50672-84-9
318 g of 1-bromo-4-bromomethylnaphthalene (II), 371.5 g of hexamethylenetetetramine, 795 g of glacial acetic acid, and 795 g of water were added to a 3L three-necked flask and reacted at reflux for 3 h at 100 °C. The reaction process was monitored by thin layer chromatography (TLC). Upon completion of the reaction, 636 g of concentrated hydrochloric acid was rapidly added dropwise for 0.5 hr. After the reaction mixture was cooled to room temperature, 4 L of water was added and stirred continuously for 3 hours. The solid product was collected by filtration, pulped with 2 L of water for 2 hours, filtered again, and the filter cake was washed twice with water, drained, and dried at 40 °C. The dried product was recrystallized with 318 g of ethanol and finally dried to give 200.4 g of 4-bromo-1-naphthaldehyde (III) in 80.4% yield. The molar ratio of 1-bromo-4-bromomethylnaphthalene (II) to hexamethylenetetetramine in the reaction was 1:2.5.
