Catalysts are substances that increase the reaction rate of a chemical reaction without being consumed in the process. 60166-93-0, Name is Iopamidol, SMILES is O=C(C1=C(I)C(NC([C@@H](O)C)=O)=C(I)C(C(NC(CO)CO)=O)=C1I)NC(CO)CO, belongs to iodides-buliding-blocks compound. In a document, author is Berkowitz, WF, introduce the new discover, Application In Synthesis of Iopamidol.
Copper-catalyzed cross-coupling of alkylsamarium reagents with alkyl halides
SmI2/HMPA converts alkyl iodides and bromides to alkyl samarium reagents which can be cross-coupled with primary alkyl iodides and bromides and secondary iodides in the presence of Cu(I) halides or Li2CuCl4 at room temperature. The alkylation of primary iodides gives good yields of cross-coupling products with negligible homo-coupling products. The method is especially useful for the small scale cross-coupling reactions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 60166-93-0 is helpful to your research. Application In Synthesis of Iopamidol.
