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.

A general approach towards catechol and pyrogallol through ruthenium- and palladium-catalyzed C-H hydroxylation by weak coordination
An efficient ruthenium(II)- and palladium(II)-catalyzed C-H hydroxylation of aryl carbamates has been developed for the facile synthesis of catechols and pyrogallols. The reaction demonstrates excellent reactivity, regio- and chemoselectivity, good functional group compatibility and high yields. The practicality of this method has been proved by a gram-scale synthesis.

Infrared Spectra and Transmission of Electronic Effects in Substituted Phenyl N,N-Dimethylcarbamates and S-Phenyl N,N-Dimethylthiocarbamates
Carbonyl stretching frequencies in CCl4 and CHCl3 and hydroxyl stretching frequency shifts of phenol as a proton donor in CCl4 were measured for series of substituted phenyl N,N-dimethylcarbamates (I) and S-phenyl N,N-dimethylthiocarbamates (II).The data
