Electric Literature of 54811-38-0, 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. 54811-38-0, name is 5-Iodo-2-methylbenzoic acid belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a reaction mixture of 150 gm of iodobenzoic acid in 750ml of dichloromethane and 3.0 ml DMF at 30C, 69.75 gm thionyl chloride was slowly charged. The reaction mixture was heated to reflux temperature of the solvent and stirred for 1 hour. The reaction mixture was cooled to 0C to 5C and was charged with 91 gm anhydrous AICI3, and 102 gm fluoro phenyl thiophene diluted in 300 ml dichloromethane. Stirred the reaction mixture at 30C for 1 hour. The reaction mixture was quenched in crushed ice water mixture at 0-5C. Organic layer was separated and washed with 750 ml saturated sodium bicarbonate solution. Dichloromethane was distilled under vacuum to obtain crude iodophenyl thiophene ketone. Crude iodophenyl thiophene ketone was recrystallized from 600 ml isopropanol to obtain 222 gm of lodophenyl thiophene ketone.
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, 5-Iodo-2-methylbenzoic acid, other downstream synthetic routes, hurry up and to see.
