Polyalkylbenzenes, with iodine

Phenylacetylene on heating with NIS in methanol and catalytic amounts of HTI was transformed to the diiodo acetal PhC(OMe)2CHI2 (95%) under similar conditions, iodo-phenylacetylene afforded PhC(OMe)2COOMe (86%) [56]. Other reactions using NBS or NIS and catalytic HTI resulted in bromination and iodination of, respectively, polyalkylbenzenes [57] and A-acyl-2,3-dihydro-4-pyridones [58]. [Pg.129]

Aromatic iodination [1, 497, after citation of ref. 12]. Polyalkylbenzenes having bulky groups are not reactive toward iodine alone but may react in the presence of an oxidizing agent. In a detailed study of agents used in this connection (silver perchlorate, mercuric oxide, iodic acid, potassium persulfate, etc.) Japanese investigators123 found the combination of iodine with periodic acid dihydrate to be the most satisfactory. [Pg.114]
