标题:Highly Chemoselective Hydrogenation With Retention Of The Epoxide Function Using A Heterogeneous Pd/c-Ethylenediamine Catalyst And Thf
摘要:In General,Palladium-Carbon (Pd/c) Catalyzed Hydrogenation Of Epoxides Affords The Corresponding Primary And Secondary Alcohols As A Mixture. It Has Been Found That The Catalytic Activity Of A Pd/c-Ethylenediamine Complex Catalyst [pd/c(En)] In The Hydrogenolysis Of Epoxide Functions Is Drastically Reduced. Herein We Describe A Mild And Chemoselective Method For The Hydrogenation Of Olefin,Nitro,And Azide Functions With Retention Of The Epoxide Function. The Chemoselectivity Was Accomplished By Using A Combination Of 5% Pd/c(En) And Thf As Solvent. A Significant Drop In The Chemoselectivity Of The Hydrogenation Is Observed With 5% Pd/c(En) In Meoh. These Results Reinforce The Utility Of Epoxides As Important Precursors Of Alcohols In Synthetic Chemistry.

标 题 :Process for the preparation of an organomercaptophenol from sulfur, a 2,6-disubstituted phenol, and an activated olefin or an epoxy compound
发明人：HAY ALLAN S
权利人:GEN ELECTRIC
摘要:A process for the preparation of an organomercaptophenol is described which comprises the reaction of sulfur with a 2,6-disubstituted phenol carried out in the presence of (1) a base, (2) an activated olefin or an epoxy compound, (3) and a solvent with a high dielectric constant. The organomercaptophenols produced by this process are useful as monomers in the synthesis of esters, carbonates, ethers, epoxy compounds, among many other chemicals synthesized from monohydric phenols. In addition, the oganomercaptophenols are also useful as antioxidants.
