| | 4-Di-p-tolylamino-benzaldehyde Usage And Synthesis |
| Chemical Properties | Light yellow - yellow-green powder | | Synthesis | N,N-dimethylformamide (2.74 g, 37.5 mmol) was slowly added dropwise to a mixed system of 4,4'-dimethyltriphenylamine (2.27 g, 18.8 mmol) and phosphorus trichloride (5.65 g, 22.5 mmol) at 25 °C. The reaction mixture was continuously stirred and heated at 130 °C for 6 hours. Upon completion of the reaction, the system was cooled to room temperature and subsequently poured into 50 mL of cold water and extracted with chloroform (3 x 15 mL). The organic phases were combined, dried with anhydrous magnesium sulfate and filtered. Purification by recrystallization from dilute ethanol afforded the target product 4-di-p-tolylaminobenzaldehyde (R2-CHO). Yield: 1.75 g (31.5% yield). The melting point of the product was 96.3-97.5 °C. Electrospray ionization mass spectrometry (ESI-MS) showed the molecular ion peak ([M + H]+) m/z was 302.4. | | References | [1] Chemical Communications, 2014, vol. 50, # 52, p. 6869 - 6871
