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. 696-41-3, name is 3-Iodobenzaldehyde, A new synthetic method of this compound is introduced below., COA of Formula: C7H5IO
(A) A stirred solution of 3-iodobenzaldehyde (25.0 g, 108.2 mmol, 1.0 eq) in DCM (400 ml) was cooled to -78 C and treated with DAST (57.0 ml, 432.9 mmol, 4.0 eq) in a dropwise manner. The RM was maintained at -78 C for 2 h, allowed to warm to RT and stirred for 16 h. The RM was quenched with cold water (100 ml), adjusted to a basic pH with sat. aq. NaHC03 and extracted with DCM (200 ml x 3). The combined organic layers were washed with water (300 ml x 2) and brine (300ml), dried (Na2S0 ), filtered and concentrated. The residue upon purification by flash chromatography (silica gel; PE – EtOAc; 100:0 to 95:5) afforded 1 -(difluoromethyl)-3-iodobenzene (23.0 g, 85%).
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.
