Sulfonic acid carbon-(bio)based and natural clays-based catalysts were prepared investigated for the first time as heterogeneous amide bond synthesis by a Ritter reaction. The different SO3H-catalysts screened using benzyl alcohol acetonitrile model substrates, MWCNT-CSP revealed to be an efficient catalyst, affording in 75 % yield. practical utility of was demonstrated diverse range amides, ob...

Density functional theory calculations were performed to investigate the reaction mechanism of aerobic oxidation benzyl alcohol benzaldehyde catalyzed by Au and Au–Pd clusters. Two consecutive mechanisms examined with Au8 Au6Pd2 clusters: (1) dissociated O atoms on metal clusters generating H2O; (2) adsorbed oxygen molecules H2O2. The show that energetically prefers proceed in former mechanism,...

3. The enzyme system could be concentrated from growth media, though with some loss, by ammonium sulphate precipitation. 4. Of the substances tested, all the primary aromatic alcohols, which included fi-naphthylcarbinol, benzyl alcohol and seven other ringsubstituted benzyl alcohols, were oxidized, but three secondary I-phenylethanols were not. Glucose, ethanol, butanol and the L-amino acids te...

Several hydrolytic reactions that transform teicoplanin or its pseudo-aglycones into the aglycone with good yields are described. The most interesting approach is hydrolytic removal of the sugars in benzyl alcohol with the formation of the aglycone benzyl ester which is then submitted to hydrogenolysis. A detailed description of the 1H and 13C NMR spectra of the teicoplanin aglycone hydrochlori...

We analyzed metabolic interactions and the importance of specific structural relationships in a benzyl alcohol-degrading microbial consortium comprising two species, Pseudomonas putida strain R1 and Acinetobacter strain C6, both of which are able to utilize benzyl alcohol as their sole carbon and energy source. The organisms were grown either as surface-attached organisms (biofilms) in flow cha...

A novel method is presented for transesterification of fatty acid esters in phospholipids and triglycerides to benzyl esters while simultaneously recovering free fatty acids as methyl esters. Transesterification is catalyzed by 0.2 M (m-trifluoromethyl phenyl)trimethyl ammonium hydroxide in methylene chloride, 10% (v/v) benzyl alcohol, and 1% (w/v) potassium tert-butoxide, and is complete in 30...

Gas phase pyrolysis of o-hydroxybenzyl alcohol at 750 degrees C gave o-quinonemethide, which, on isolation, formed a mixture of the corresponding dimer and trimer. However, pyrolysis of o-hydroxy-[1-(4-pentenyl)]benzyl alcohol permitted intramolecular trapping of the intermediate o-quinonemethide, giving 3,4-trimethylene-3,4-dihydrobenzochroman. In contrast, gas phase pyrolysis of o-mercaptoben...
