626-01-7, Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 626-01-7, name is 3-Iodoaniline, A new synthetic method of this compound is introduced below.
General procedure: In a 10-ml round-bottom flask equipped with a condenser, a mixture of the aromatic amine (2 mmol), ethyl acetoacetate (1 mmol), and [Pyridinium-SO3H]HSO4 (0.0,385 g, 15 mol %) was stirred at 100 C for 10 min. Afterwards, the aromatic aldehyde (2 mmol) was added, and the resulting mixture was kept under stirring for the specified time in Table 3, the progress of the reaction was followed by TLC. After completion of the reaction, the reaction mixture was cooled to room temperature, extracted by the warm EtOAc (10 ml) to separate the catalyst. EtOAc was removed and the crude product was recrystallized from aqueous ethanol (96 %) to afford the pure product, which required no further purification. The recovered catalyst was washed with EtOAc (2 x 10 ml), dried, and reused, without considerable catalytic activity decrease.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
