A series of Fe mixed picolinate and quinaldinate complexes that catalyze the H2O2 oxidation of alcohols are presented. The Fe catalysts are generated in situ by simple mixing of iron acetate with 6-methylpicolinic acid (6-MepicH) and 4-chloropicolinic acid (4-ClpicH); they showed high catalytic activity for H2O2 oxidation of 1-phenylethanol to acetophenone. Fe complexes generated in situ as precatalysts were successfully isolated and structurally characterized. Based on the single-crystal X-ray analysis and electrochemical measurements of the Fe complexes, the lability of picolinate and/or quinaldinate ligand and the redox potential of FeIII were found to be important factors for the catalytic reaction.

The methylenation of allenes H2C=C=CHR1 II (R1=H, C6H5, OCH3) by carbene iron complexes (CO)4Fe=C(OEt)R I (R=C6H5, CH3) leads to the formation of trimethylenemethane iron complexes.In this reaction the carbene ligand is attached in an unusual way to the c

The enol isomer of isobutyrophenone was generated in aqueous solution from its alkali-metal enolates, and rates of ketonization of the enol in this solvent were measured under catalysis by HCl, NaOH, H3PO4, H2PO4(1-), six carboxylic acids (RCO2H), and six

An electrochemistry-promoted oxidative cleavage of (sp3)C-C(sp3)/H bonds in alkylarenes was developed. Various aryl alkanes can be smoothly converted into ketones/aldehydes under aerobic conditions using a user-friendly undivided cell setup. The features of air as oxidant, scalability, and mild conditions make them attractive in synthetic organic chemistry.

Indolyl fragment containing phenanthroline based new ligands and their corresponding Ru(ii) complexes were synthesized and fully characterized by various spectroscopic techniques. The catalytic activity of these newly synthesized cyclometalated (NNC)Ru(ii) complexes was explored towards the β-methylation of alcohols using methanol. Notably, these complexes displayed superior reactivity compared to various (NNN)Ru(ii) complexes. Utilizing this strategy, a wide range of primary, secondary, and aliphatic straight chain alcohols were selectively methylated. This protocol was further employed for the methylation of a few natural products and the gram scale synthesis of β-methylated alcohols. A series of control experiments and kinetic studies were performed to understand the plausible reaction mechanism.

An iron-sulfur complex formed by the simple mixture of FeCl3 with S3?- generated in situ from K2S is developed and applied to selective aerobic oxidation of terminal alkenes. The reaction was carried out under an atmosphere of O2 (balloon) and could proceed on a gram scale, expanding the application of S3?- in organic synthesis. This study also encourages us to explore the application of an Fe-S catalyst in organic reactions.
