Pd(II) catalyzed ortho C–H iodination of phenylcarbamates at room temperature using cyclic hypervalent iodine reagents

A novel approach to access ortho iodinated phenols using cyclic hypervalent iodine reagents through palladium(II) catalyzed C–H activation has been developed through weak coordination. The reaction showed excellent regioselectivity, reactivity and good functional group tolerance. A unique mechanism was proposed.

Ngurah Rai International Airport is located in southern Bali. The capital of Bali, Denpasar, is located nearby.
The airport is named after I Gusti Ngurah Rai, an Indonesian republican who died on 20 November 1946 in a puputan (fight to the death) against the Dutch. The Dutch defeated his company with air support, killing Rai and 95 others during the Indonesian Revolution in 1946. The airport is located in Tuban between Kuta and Jimbaran and is close to the tourist locations of southern Bali; the resort center of Kuta is 2.5 km north of the airport.
