2-Bromoresorcinol Chemical Properties,Usage,Production
Synthesis
To 500 ml four-necked bottle successively added 170 g of toluene and 9.4 g of tert-butylamine, cooled down to -30 ??, 10.4 g of bromine slowly added dropwise, drop after drop, and then cooled down to -60 ??, dropwise addition of dichloromethane solution of catechol, drop after a natural warming to room temperature reaction for 24 hours, the sample is sent to the control of the HPLC; the end of the reaction, saturated sodium bisulfite quenched, dilute hydrochloric acid to adjust the pH = 1, toluene Toluene extraction, spinning to remove toluene; crude product and then distillation under reduced pressure to obtain the compound 2-bromocatechol. Yield 74-80%, HPLC ?? 98%. This method is simple, safe and reliable, with high yield, suitable for industrialized production and the synthesis of 3-bromocatechol, which is a pharmaceutical intermediate with large socio-economic and environmental benefits.
Properties and Applications
The cyclocondensation of 2-bromoresorcinol with some aldehydes proceeds in acetonitrile-CF3SO3H to give cyclic tetramers with high stereoselectivity. 2-bromoresorcinol, C6H5BrO2, are essentially planar and possess normal geometrical parameters. The crystal packing is influenced by O-H...O and O-H...O/Br hydrogen bonds and pi-pi stacking interactions, resulting in a distinctive high-symmetry structure containing R(4)(4)(8) rings and helical C(2) chains[1-2].
