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. 7681-82-5, name is Sodium iodide, A new synthetic method of this compound is introduced below., Application In Synthesis of Sodium iodide

General procedure: A typical example is exemplified by the synthesis of 4b: To a stirred solution of TMEDA (1.36 mL,9 mmol) in hexane (5 mL) was added dropwise at ice bath temperature n-butyllithium (9 mmol) in hexane followed by acetophenone trimethylsilyl enol ether 1 (576 mg, 3 mmol), and the mixture was stirred for 24 h at room temperature. In a separate flask, a mixture of bismuth(III) chloride (315.5 mg,1 mmol) and tris(4-methylphenyl)bismuthane (964 mg, 2 mmol) was stirred in ether (10 mL) at room temperature for 1 h. To the suspension of chlorobis(4-methylphenyl)bismuthane (ca. 3 mmol) thus formed was added sodium iodide (450 mg, 3 mmol) and a few drops of 15-crown-5 ether and the resulting yellowish mixture was stirred for 3 h at room temperature. To a suspension of the lithium compound previously prepared was added at room temperature magnesium dibromide diethyl etherate (775 mg, 3 mmol) followed by, at -30 C, a suspension of iodobis(4-methylphenyl)bismuthane(ca. 9 mmol), and the resulting mixture was stirred for 1 h, during which time the temperature was raised to ambient temperature. The reaction mixture was poured into brine (50 mL) and extracted with ethyl acetate (50 mL ¡Á 3). The combined extracts were concentrated to leave an oily residue, which was purified by chromatography (silica gel) using hexane-ethyl acetate (5:1) as the eluent to afford 4b in 30% yield (459 mg, 0.9 mmol). Because 4a, 4f and 10 underwent decomposition when purified by chromatography on silica gel, these compounds were converted into the corresponding halobismuthanes 5a, 5f and 11, respectively, without isolation.

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.
