Cross-coupling of benzylic acetates with arylboronic acids: one-pot transformation of benzylic alcohols to diarylmethanes.

Benzylic acetates reacted with arylboronic acids in the presence of a DPEphos-[Pd(eta3-C3H5)Cl]2 catalyst when tert-amyl alcohol was used as a solvent, and the catalytic cross-couplings produced diarylmethanes in high yields (up to 94% isolated yield).

Selective oxidation of benzyl alcohols to benzaldehydes using a membrane contactor

In this work, we report a novel method for selective oxidation of benzyl alcohols to benzaldehydes. Neither solvent nor promoters are needed: a polymeric microporous membrane acts as a barrier to “keep in contact” the two phases: the organic phase containing the substrate, benzyl alcohols and the products, benzaldehydes and the aqueous phase with the catalyst and the oxidant, hydrogen peroxide....

Shape-Selective Oxidation of Benzylic Alcohols by a Receptor Functionalized with a Dicopper(II) Pyrazole Complex

A novel metallohost containing a substrate-binding site and two copper ions held by two bis-pyrazole ligand sets is described. The cavity of this molecule can bind dihydroxybenzene guests (association constants in chloroform are in the range K& = 2000-3000 M-1). In the presence of benzylic alcohols the Cu(II) centers of the metallohost are reduced to Cu(I). During this process the alcohols are ...

Co(III)@Fe3O4@SiO2 salen complex as a highly selective and recoverable magnetic nanocatalyst for the oxidation of sulfides and benzylic alcohols

In this study, Co (III) salen complex was synthesized and immobilized onto the surface of Fe3O4@SiO2 magnetic nanoparticle. The heterogeneous nanocatalyst was characterized by different techniques including X-ray diffraction (XRD), Fourier transform infrared spectra (FT-IR), thermogravimetric analysis (TGA), transmission electron microscopy (TEM), nitrogen adsorption−desorption isotherm (BET), ...

Oxidation of allylic and benzylic alcohols to aldehydes and carboxylic acids.

An oxidation of allylic and benzylic alcohols to the corresponding carboxylic acids is effected by merging a Cu-catalyzed oxidation using O2 as a terminal oxidant with a subsequent chlorite oxidation (Lindgren oxidation). The protocol was optimized to obtain pure products without chromatography or crystallization. Interception at the aldehyde stage allowed for Z/E-isomerization, thus rendering ...
