In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 696-41-3, name is 3-Iodobenzaldehyde belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. Recommanded Product: 3-Iodobenzaldehyde
General procedure: Triton B (40% in MeOH, 7.30 mL, 17.5 mmol) was added dropwise to a solution of ethyl 2-[bis(2-isopropylphenoxy) phosphoryl]acetate (5.30 g, 13.1 mmol) in THF (150 mL) at -78 C under Ar. After 15 min of stirring, a solution of 2-methylbenzaldehyde (59) (1.50 g, 12.5 mmol) in THF (50 mL) was added dropwise to the solution. After 10 h of stirring, the mixture was quenched with satd. aq. NH4Cl (30 mL) and extracted with EtOAc (3 x 30 mL). The organic layer was washed successively with H2O, satd. aq. (20 mL) NaHCO3 (20 mL) and brine (20 mL), then dried (MgSO4), filtered and concentratedin vacuo.; Z-selective olefination of 3-iodobenzaldehyde (87) was performedusing the procedure described above to provide (Z)-ethyl3-(3-iodophenyl)acrylate (cis-143) (94%, Z:E = 98:2, determinedby 1H-NMR spectrum) (silica gel CC, EtOAc/hexane, 5:95) as acolorless oil: 1H-NMR (CDCl3, 270 MHz) d: 1.26 (t, J = 7.2 Hz, 3H,-CH3), 4.19 (q, J = 7.2 Hz, 2H, -CH2-), 5.98 (d, J = 12.6 Hz, 1H,CH-CO2-), 6.85 (d, J = 12.6 Hz, 1H, Ar-CH), 7.10 (t, J = 7.8 Hz,1H, Ar-H), 7.53, 7.66 (d, J = 7.8 Hz, each 1H, Ar-H), 7.90 (s, 1H,Ar-H).
The synthetic route of 696-41-3 has been constantly updated, and we look forward to future research findings.
