4-Bromo-9H-carbazole Chemical Properties,Usage,Production

Chemical Properties

White powder.

Uses

4-BroMo-9H-carbazole is a useful research chemical. 4-BroMo-9H-carbazole is a bromide-substitution of carbazole. The carbazole ring system is essentially planar (r.m.s. deviation of 0.024A for the non-H atoms). It is a photoelectric material intermediate and be used to synthesize OLED materials.    

Hazard

H315 (100%): Causes skin irritation [Warning Skin corrosion/irritation]
H319 (100%): Causes serious eye irritation [Warning Serious eye damage/eye irritation]

Synthesis

Under nitrogen protection,Add 357.6g m-dibromobenzene (99%, 1.5mol) into a 500mL reaction flask,26.1g o-bromoaniline (99%, 0.15mol),0.084g palladium(II) acetate (99%, 0.375mmol),0.18g 2-dicyclohexylphosphine-2,4,6-triisopropylbiphenyl (99%, 0.375mmol),58.2g sodium tert-butoxide (99%, 0.6mol),After feeding,Warm up to 130°C,Stirring speed 600rpm,Incubate for 24hr,After the reaction,Vacuum distillation to recover unreacted m-dibromobenzene,Add water and ethyl acetate to extract the residue,The organic layer was desolvated to obtain the crude product which was crystallized in ethanol to obtain 34.3 g of 4-BroMo-9H-carbazole.The content is 99.6% and the yield is 92.5%.
