- Transition-metal-free carbonylation of aryl halides with arylboronic acids by utilizing stoichiometric CHCl3 as the carbon monoxide-precursor
-
Under transition-metal-free conditions, carbonylative Suzuki couplings of aryl halides with arylboronic acid using stoichiometric CHCl3 as the carbonyl source has been developed. The simple, efficient, and environmentally benign method was successfully applied to the synthesis of Fenofibric acid, naphthyl phenstatin, and carbon-13 labeled biaryl ketone.

- Transition-Metal-Free Carbonylative Suzuki-Miyaura Reactions of Aryl Iodides with Arylboronic Acids Using N-Formylsaccharin as CO Surrogate
-
Unprecedented, high yielding, transition-metal-free carbonylative Suzuki-Miyaura reactions of aryl iodides with arylboronic acids using N-formylsaccharin as CO surrogate have been developed. Notably, this general protocol was adapted to the synthesis of the triglyceride and cholesterol regulator drug, fenofibrate, and carbon-13 labeled biaryl ketone. (Figure presented.).

- Pd-NHC catalysed Carbonylative Suzuki coupling reaction and its application towards the synthesis of biologically active 3-aroylquinolin-4 (1H)-one and acridone scaffolds
-
We have unfolded a convenient and mild protocol for the synthesis of diaryl ketones via Pd- NHC catalysed carbonylative Suzuki coupling reaction. Notably, this method offers advantages like no use of toxic CO gas, shorter reaction time, high yield, and broad substrate scope. Several sensitive functional groups (like-COMe, -COOMe, -F, -Cl, -Br, -NH2, -CN) are well tolerated in this reaction. In addition, we have also demonstrated a new efficient route for the synthesis of biologically active and pharmaceutically important 2-substituted 3-Aroylquinolin-4(1H)-ones and acridone scaffolds.

- A synthesis of biaryl ketones via the C–S bond cleavage of thiol ester by a Cu/Ag salt
-
We report the synthesis of biaryl ketones via an unprecedented copper/silver catalyzed acylative cross-coupling of thiol esters with either an arylboronic acid or a potassium aryltrifluoroborate. This new method proceeds without a requisite Pd-catalyst and Cu(I)TC mediator, and is efficient, versatile, operationally simple, and accommodating functionally diverse thiol esters, arylboronic acids, and potassium aryltrifluoroborates.

- Aromatic ether-ketone polyamines, intermediates and products, and methods for preparing same
-
Novel aromatic ether ketone diamine compounds and methods for their preparation are disclosed which comprise from about 3 to 8 aromatic rings interspersed with ether and ketone linkages. The novel ether ketone diamine compounds are useful as monomeric starting materials for the preparation of useful intermediates and useful thermoplastic and high temperature resistant polymers. In preferred embodiments, the novel ether ketone diamines are useful as curing agents for epoxy resin compositions and composite materials.
