Treatment of Alcohols with Tosyl Chloride Does Not always Lead to the Formation of Tosylates

open access: yesMolecules, 2011
Treatment of substituted benzyl alcohols with tosyl chloride resulted in the formation of the corresponding chlorides, not the usual tosylates. A series of experiments demonstrated that it was possible to predict whether chlorination or tosylation would ...

Synthesis of Cycloveratrylene Macrocycles and Benzyl Oligomers Catalysed by Bentonite under Microwave/Infrared and Solvent-Free Conditions

open access: yesMolecules, 2013
Tonsil Actisil FF, which is a commercial bentonitic clay, promotes the formation of cycloveratrylene macrocycles and benzyl oligomers from the corresponding benzyl alcohols in good yields under microwave heating and infrared irradiation in the absence of

Hydroxylamine-mediated C–C amination via an aza-hock rearrangement

open access: yesNature Communications, 2021
Syntheses of anilines occur through a variety of methods, most requiring transition metals or multiple steps. Here the authors disclose a protocol to form anilines from benzyl alcohols via an aza-Hock rearrangement that uses only a sulfonyl hydroxylamine

Transformation of Tertiary Benzyl Alcohols into the Vicinal Halo-Substituted Derivatives Using N-Halosuccinimides

open access: yesMolecules, 2016
The efficiency of direct conversion of tertiary alcohols bearing a β-hydrogen atom to vicinal halohydrins—chlorohydrins and bromohydrins—under green reaction conditions was tested preliminarily on model tertiary benzyl alcohols.

Kinetics and Oxidation of Substituted Benzyl Alcohols by Phenyliodoso Acetate

open access: yesE-Journal of Chemistry, 2011
Oxidation of benzyl alcohol and some meta- and para- substituted alcohols by phenyliodoso acetate (PIA) in t-butyl alcohol–water medium (50:50) leads to the formation of corresponding benzaldehyde.

Handy and highly efficient oxidation of benzylic alcohols to the benzaldehyde derivatives using heterogeneous Pd/AlO(OH) nanoparticles in solvent-free conditions

open access: yesScientific Reports, 2020
The selective oxidation of benzylic alcohols was performed by using commercially available aluminum oxy-hydroxide-supported palladium (Pd/AlO(OH)) nanoparticles (0.5 wt.% Pd, about 3 nm size) under mild conditions.
