CuCl/CuCl2/I2 a-iodination of propanoic acid - 90%
« on: May 07, 2004, 09:04:00 PM »

chem.lett. - 1984 - 1509/1510

alpha iodopropanoic acid (brief summary, read the 2 page .djvu!)

CuCl (0.5 mol equiv), CuCl2 (0.5 mol equiv), I2(1 mol equiv) and propanoic acid (excess) are mixed and reacted at 120°C for 6h under N2 atmosphere. Precipitated copper salts are filtered, excess acid is distilled off, product is recrystallized from hexane to afford a 90% yield based on I2.



where to go from here ?
