화학적 성질
yellow crystalline solid용도
2-Chloro-1-methylpyridinium iodide is a reagent in a wide variety of dehydrative coupling reactions. It is also used to form carboxylate esters from acids and alcohols, carboxamides from acids and amines, lactones from -hydroxy acids and carbodiimides from N,N-disubstituted thioureas.일반 설명
2-Chloro-1-methylpyridinium iodide (Mukaiyama reagent), is a commonly used reagent in organic synthesis for the activation of the hydroxy group of alcohols and carboxylic acids. It is used to synthesize derivatives of esters, lactones, amides, lactams, and ketenes from the corresponding carboxylic acids. It is also used as an efficient coupling reagent in the synthesis of peptides because of its low toxicity, simple reaction conditions, and also less expensive than EDC.Purification Methods
Purify it by dissolving in EtOH and adding dry Et2O. The solid is washed with Me2CO and dried at 20o/0.35mm. Store it in the dark. Attempted recrystallisation from Me2CO/EtOH/pet ether (b 40-60o) causes some exchange of the Cl substituent by I. The picrate has m 106-107o, and the perchlorate has m 212-213o. [Jones et al.
