Periodic acid dihydrate, with iodine and

Periodic acid dihydrate, with iodine and durene to give iododurene, 51, 94 Phenols, from aryl methyl ethers, 53, 93 Phenylacetaldehyde, from 2-lithio-1,3,5-trithiane and benzyl bromide, 51, 43 Phenylacetic acid, bromination, 50, 31... 

Aromatic iodination (2, 220). In a procedure for the preparation of iododurene,3 a mixture of 13.4 g. (0.1 mole) of durene, 4.56 g. (0.02 mole) of periodic acid dihydrate, and 10.2 g. (0.04 mole) of iodine is stirred magnetically under reflux and treated with a... 

For iodination of 13.4 g. (0.1 m.) of durene, Suzuki introduced this amount of hydrocarbon into a 200-ml. two-necked flask fitted with a reflux condenser, a (hermometer, and a magnetic stirrer and added 4.56 g. (0.02 m.) of periodic acid dihydrate, 10.2 g. of iodine (0.04 m.), 100 ml. of acetic acid, 20 ml. of water, and 3 ml. of coned, sulfuric acid. The mixture was heated to 65-70° with stirring until the color of iodine disappeared (about 1 hr.). The mixture was then diluted with...
