Reference of 3032-81-3, A common heterocyclic compound, 3032-81-3, name is 1,3-Dichloro-5-iodobenzene, molecular formula is C6H3Cl2I, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
Preparation of 1,3-dichloro-5-iodo-2-methylbenzene To the mixture of LDA (5 mL, 8.6 mmol) in THF (20 mL) was added compound 1,3-dichloro-5-iodobenzene (2.35 g, 8.6 mmol) under -78° C. Then the mixture was added to the pre-cooled solution of (CH3)2SO4 (12 mL, 10.3 mmol) in THF (10 mL) under -78° C. The solution was concentrated under vacuum. The residue was diluted with EA, washed with 1N HCl, 1N NaOH, brine, dried over Na2SO4, concentrated under vacuum to give the desired product (2.3 g, 93percent yield).
The synthetic route of 3032-81-3 has been constantly updated, and we look forward to future research findings.
