A tandem electrosynthesis of homoallylic alcohols from alcohols in one-pot was realized. In virtue of this one-pot electrosynthesis, the traditional reaction substrates of allylation were broadened from carbonyl compounds to alcohols.

Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...

mn(ii) salen complex immobilized on nano silicagel was prepared by incorporating mn(ii) salen complex into a nanosilica matrix and characterized by tga, xrd, atomic absorption spectroscopy and was successfully applied as catalyst for the oxidation of alcohols. oxidation of a series of alcohols in acetonitrile over immobilized mn(ii) salen complex using tetrabutylammonium peroxymonosulfate (tbao...

The enantioselective silylation of racemic alcohols, where one enantiomer reacts faster than the other, is an alternative approach to established enzymatic and non-enzymatic acylation techniques. The existing art is either limited to structurally biased alcohols or requires elaborate catalysts. Simple substrates, such as benzylic and allylic alcohols, with no coordinating functionality in the p...

Esterification of several carboxylic acids with supercritical alcohols such as 1-propanol, 1butanol, 1-octanol, isoamylalcohol, ethanol, methanol, and subcritical benzyl alcohol without using any catalyst was studied. A variety of esters were synthesized very effectively using supercritical alcohols as solvent and reagent. Moderate to excellent yields were obtained depending on the nature of th...

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 occur for substituted benzyl alcohols and pyridine methanols. Treatment of electron withdrawing group-substituted benzyl alcohols with tosyl ch...

Wound healing disorders including diabetic ulcers, chronic venous leg ulcers and pressure are still remains uncured pose a stern challenge to health care system. Accumulation of dysfunctional macrophages over time have been identified as major underlying cause for wounds, however molecular events regulating these unclear. In present study, we found that histone H3K27 acetylation, an epigenetic ...

fibers of poplar wood (populus nigra l.) were prepared and oven dried. afterwards, they were acetylated with acetic anhydride without a catalyst. acetylation was carried out for different durations at 120ºc. different weight percentage gains (wpgs) were achieved based on the operating conditions. acetylated fibers were exposed to varying levels of relative humidity to determine equilibrium mois...

trimethylsilylation of a variety of alcohols and phenols, in the presence of silica chloride, using hexamethyldisilazane (hmds) in solution and under solvent-free conditions is reported. trimethylsilyl ethers were formed in excellent yields both for aliphatic alcohols and phenols without having an electron-withdrawing group. in addition, sio2-cl can be recovered and reused after drying.
