| | DIETHYL BROMOMALONATE Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS TO SLIGHTLY YELLOW LIQUID | | Uses | Diethyl Bromomalonate is a chemical constituent of the asymmetric cyclopropanation of chalcones. Also used in the preparation of nanaplatforms for NIR imaging-guided photodynamic therapy of cancer cel
ls. | | Uses | Diethyl bromomalonate is used in perfumes. It is also used to synthesize other compounds such as barbiturates, artificial flavorings, vitamin B1, and vitamin B6. | | Synthesis | The Preparative Method of Diethyl Bromomalonate: by light-induced bromination of Diethyl Malonate with bromine in carbon tetrachloride; by treatment of diethyl malonate with bromotrichloromethane and 1,8-Diazabicyclo[5.4.0]undec-7-ene in benzene at 0 °C.
| | Purification Methods | Purify the ester by fractional distillation in a vacuum. IR: max 1800 and 1700cm-1 [Abramovitch Can J Chem 37 1146 1959, Bretschneider & Karpitschka Monatsh Chem 84 1091 1053]. [Beilstein 2 IV 1904.] |
