Three different substituted thiazoles have been successfully synthesized from readily available propargylic alcohols. Various secondary propargylic alcohols or tertiary propargylic alcohols participated well in the reaction, providing the desired products in good yields. This method provides a flexible and rapid route to substituted thiazoles.

An economic and practical AIBN-initiated aerobic oxidation system of benzylic alcohols, hetero aryl alcohols and allyl alcohols was developed for the first time. Moderate to excellent yields were obtained with a broad substrate scope. Moreover, a proposed mechanism of a radical process was assumed and confirmed by the key intermediate detected.

A simple method has been developed for the reductive deoxygenation of aromatic ketones and benzylic alcohols in the presence of polymethylhydrosiloxane (PMHS). The reductive deoxygenation of aromatic ketones and benzylic alcohols, including secondary alcohols, to the corresponding methylene hydrocarbons has been achieved in good to excellent yields using palladium chloride (PdCl2) as catalyst a...

The present work reports the Metschnikowia koreensis-catalyzed one-pot deracemization of secondary alcohols/1,2-diols and their derivatives with in vivo cofactor regeneration. Reaction is stereoselective and proceeds with sequential oxidation of (R)-secondary alcohols to the corresponding ketones and the reduction of the ketones to (S)-secondary alcohols. Method is applicable to a repertoire of...

Electrooxidation of urea plays a substantial role in the elimination urea-containing wastewater and industrial urea. Here, we report electrodeposition nickel hydroxide catalyst on commercial carbon paper (CP) electrodes from dimethyl sulphoxide solvent (Ni(OH)2-DMSO/CP) for electrooxidation under alkaline conditions. The physicochemical features Ni(OH)2-DMSO/CP catalysts using scanning electron...

Sweeney, Edward E. (University of California, Los Angeles) and Gregory J. Jann. Utilization of carbohydrates and polyhydric alcohols by Mycobacterium tuberculosis. J. Bacteriol. 84:459-465. 1962.-A new procedure, using a massive inoculum and nongrowth basal medium, was employed for testing carbohydrate and polyhydric alcohol utilization by human tubercle bacilli. A positive reaction was represe...

Two kinds of fluorinated polymers were synthesized: an acrylate polymer having a fluorinated triethylene glycol as a pendant group (2a) and a fluoroalkyl acrylate polymer (2b). The contact angle of these fluorinated polymers against water, non-fluorinated alcohols and fluorinated alcohols were evaluated. As compared with the fluoroalkyl polymer (2b), fluoroethylene glycol polymer (2a) showed sm...

Carbonylruthenium tetrakis(pentafluorophenyl)porphyrin Ru(TPFPP)(CO) was utilized for the aerobic oxidation of alcohols. The in situ activation of the catalyst with mCPBA provided a species capable of catalyzing the oxidation of alcohols with molecular oxygen. The choice of solvent and additive was crucial to obtaining high activity and selectivity. Secondary aromatic alcohols were oxidized in ...
