A sulfur-containing auxiliary enabled palladium-catalyzed C(carbonyl)–C bond activation of amides was reported to form phenylcarbamate derivatives with alcohols. Both alkyl and benzyl alcohols could be employed well with yields up to 85%. Derivations from phenylcarbamates to ureas and thiocarbamates illustrated the potential applications of this sequential C–C cleavage/C–O coupling reaction.

Transition metal catalyzed coupling of thiols with aryl iodide offers a convenient method for accessing C–S linkage in organic synthesis. Herein, we report an efficient and practical method for the C–Scrosscoupling of thiophenols with aryl iodides using a Cu(I) catalyst. A diverse set of thiophenols is coupled with electron rich and poor aryl iodides to obtain diaryl sulfides in good to excellent
This invention relates to aryl carbonyl derivatives which are activators of glucokinase which may be useful for the management, treatment, control, or adjunct treatment of diseases, where increasing glucokinase activity is beneficial.

Chelate resins, which are polystyrene-divinylbenezene-based polymers bearing iminodiacetic acids or polyamines as ligands, supported copper catalysts (Cu/CR11 or Cu/CR20) in effectively catalyzing the ring cleaving S-arylation of benzothiazole with aryl iodides or aryl bromides in the presence of lithium tert-butoxide in aqueous 2-propanol.
