Tetraethoxysilane → HCID 57894271, compound

Participants

Reaction Steps

Firstly, 2-M i-PrMgCl (24 mL (solvent: THF, 48 mmol) was added dropwise to a mixture of 1,4-diiodobenzene (15 g, 45.6 mmol) and dist. THF (114 mL) at −30° C. Then the resultant mixture was stirred under a nitrogen atmosphere at −30° C. for 5.5 hours to obtain a reaction solution. Subsequently, the reaction solution was added dropwise (3 drops/second) using a cannular into a mixture of tetraethoxysilane (TEOS: 60.6 mL, 272 mmol) and dist. THF (90 mL), which was cooled to −30° C. The resultant mixture was stirred at −30° C. for 1 hour, and then was stirred at room temperature for 44 hours to obtain a reaction mixed solution. Thereafter, the obtained reaction mixed solution was added with ether (100 mL), and then was washed with distilled water (dist. H2O). After that, an aqueous layer was extracted with ether. Then, an organic layer thus collected was washed with sat. NaCl, and was dried with MgSO4. The dried organic layer was filtered and concentrated to obtain a crude product. Subsequently, the obtained crude product was purified by a reduced-pressure distillation process (1.5 mmHg, 120° C.) to obtain 4-(triethoxysilyl)iodobenzene (10.2 g, 61% yield).
