A common compound: 31599-60-7, name is 1-Iodo-2,3-dimethylbenzene, belongs to iodides-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 31599-60-7
General procedure: A DMF solution (8mL) of the o-substituted aryl iodide (0.36mmol), the o-bromobenzyl alcohol (0.36mmol) and norbornene (34mg, 0.36mmol) was added under nitrogen to a Schlenck-type flask, containing Pd(OAc)2 (4mg, 0.018mmol), the phosphine (0.036mmol), when required, and K2CO3 (124mg, 0.90mmol) or CsOPiv (211mg, 0.90). The reaction mixture was stirred at 105C for 24h. After cooling to room temperature the organic layer was diluted with EtOAc (20mL), washed twice with water (20mL) and dried over Na2SO4. The solvent was removed under reduced pressure and the resulting residue was purified by flash chromatography on silica gel using mixtures of hexane-EtOAc as eluent.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 31599-60-7, other downstream synthetic routes, hurry up and to see.
