용도
4-Iodobenzaldehyde is used in synthesis of 4-[2-(trimethylsilyl)ethynyl]benzaldehyde, 5,15-dimesityl-10-(3-[2-(trimethylsilyl)ethynyi]phenyl}-20-(4-iodophenyl)porphyrin, and 5,15-dimesityl-10-[3,5-bis{2-[4-(N,N?-difluoroboryl-1,9-dimethyidipyrrin-5-yl)-phenyl]ethynyl}phenyl]-20-(4-iodophenyl)porphyrin.
Synthesis
A mixture of 10.0g p-bromobenzaldehyde (54mmol), 81.1gKI (488mmol, 9.0eq), 31.7gCuI (166mmol, 3.1eq) and 150ml freshly distilled DMI was placed in a 500ml three-neck flask. The mixture was purged with nitrogen and heated at 200°C with vigorous stirring for 6 hours. After cooling to room temperature, add salt water and ice. The reaction vessel was placed in an ice bath for several hours and precipitated inorganic salts were removed by filtration. After the filtrate was extracted with diethyl ether, the extracts were combined and washed with brine. Removal of the solvent under reduced pressure gave the product 4-Iodobenzaldehyde.
