Selective photocatalytic aerobic oxidation, which can be conducted under ambient conditions, is of great importance towards achieving sustainable chemistry. However, its practical applications are undermined by several challenges, such as low selectivity, sluggish reaction rates, and the requirement of UV light irradiation. Herein, we report a new concept of synergistic photocatalytic oxidation...

Enantioenriched alcohols are ubiquitous in the structures and syntheses of natural products and pharmaceuticals. Catalytic, asymmetric alcohol oxidation can be a useful method to access these molecules.[1] Previously, we reported the development of an aerobic kinetic resolution of alcohols by catalytic [Pd(nbd)Cl2] (1, nbd = norbornadiene) and the naturally occurring alkaloid (−)-sparteine (sp,...

CuBr(2) with 2,2,6,6-tetramethylpiperidyl-1-oxy (TEMPO) has been successfully employed for the aerobic oxidation of primary and secondary benzyl amines in aqueous acetonitrile. Such catalytic systems have previously been used extensively in alcohol oxidation reactions. The same catalyst system was also used for oxidative cross-couplings of benzylamines with anilines. The electronic and steric p...

Introduction 5-Hydroxymethyl-2-furaldehyde (HMF), as diformylfurane precursor (DFF), is obtained from fructose or glucose dehydration. DFF is a versatile chemical, and there are numerous reports describing various applications as a monomer, as starting materials for the synthesis of pharmaceuticals and antifungal agents [1]. To date, few reports describe the use of air to oxidize (HMF) with het...

Abstract In this paper, mono-metallic catalysts, palladium (Pd) and gold (Au) bi-metallic, Au-Pd supported on reduced graphene oxide (rGO) synthesized by Sol Immobilization technique. The as fabricated catalysts (Pd/rGO, Au/rGO Au-Pd/rGO) have been tested various techniques (Raman Spectroscopy, FE-SEM, XRD TEM) to examine the structural, compositional morphological characteristics. performance ...

In the present research, the selective oxidation of lauryl alcohol to lauraldehyde was studied under liquid-liquid phase transfer conditions using potassium chromate (K2CrO4) as an oxidizing agent and tetrabutyl ammonium bromide (TBAB) as the phase transfer catalyst. Chromium (VI) reagents are used in these oxidations since the alcohols are selectively oxidized <e...
