A variety of aromatic, aliphatic and conjugated aldehydes were converted to the corresponding carboxylic acid derivatives with 30% H2O 2 as the oxidant in the presence of catalytic amounts of AgNO 3. The method described has wide range of applicabilities, does not involve cumbersome work-up, exhibits chemoselectivity and proceeds under mild reaction conditions, and the resulting products are obtained in good yields within reasonable time. © 2009 Elsevier Ltd.

A direct synthetic route for the C-S coupling of aryl halides with thiophenols is described. This method is tolerant to electron-withdrawing and electron-donating functional groups and also to the presence of functional groups in the ortho position of the aryl iodide or thiophenol. Aryl iodides are coupled with thiophenols without affecting the other functionalities present in the aryl ring. These reactions follow second-order kinetics. Copyright © 2012 John Wiley & Sons, Ltd.

Bi(III)-catalyzed C-S cross-coupling reaction

AgOTf proved to be an effective catalyst for the transesterification of β-keto esters with primary, secondary and tertiary alcohols. The products were obtained in high yield within a reasonable reaction time period. The kinetics of the transesterification reaction were also studied and the reaction was found to follow second-order kinetics. Copyright © 2012 John Wiley & Sons, Ltd.

AgOTf-catalyzed transesterification of β-keto esters

Various aromatic, aliphatic and conjugated aldehydes were transformed to the corresponding carboxylic acids with 70% t-BuOOH solution (water) in the presence of catalytic amounts (10 mol%) of Mohr's salt. This method possesses functional group compatibility, does not involve cumbersome work-up, exhibits chemoselectivity since other functional groups remain intact and proceeds under mild conditions. The resulting products are obtained in good yields within reasonable times. Copyright © 2011 John Wiley & Sons, Ltd.

FeIII-catalyzed synthesis of primary amides from aldehydes

Aromatic aldehydes possessing a wide variety of substituents were smoothly converted to carboxylic acids in excellent yields by stoichiometric bismuth(III) nitrate pentahydrate in presence of aerial oxygen in a microwave-oven under solvent-free conditions. The method is environmentally benign being solvent-free, operationally simple, highly chemoselective, employing no cumbersome work-up procedures, having wide general applicability, short reaction times, mild reaction conditions, large scale-ups and very good yields. © 2008 Elsevier B.V.
