Multiply iodinatedbiaryls can be prepared in yields up to 75% by direct oxidative coupling reaction of the iodinated arenes. The PIFA-mediated dehydrodimerization is superior to all other known methods. The developed protocol is reliable and easy to perform.

The chlorination of electron rich iodoarenes with MoCl5 proceeds with methoxycarbonylmethyl as the directing group. The transformation is selective and without loss of the valuable iodo substituent.
