Fatty alcohols are value-added chemicals and important components of a variety of industries, which have a >3 billion-dollar global market annually. Long chain fatty alcohols (>C12) are mainly used in surfactants, lubricants, detergents, pharmaceuticals and cosmetics while medium chain fatty alcohols (C6-C12) could be used as diesel-like biofuels. Microbial production of fatty alcohols from ren...
Herein, a stepwise electrodeposition technique was used to synthesize the Pd based nanoparticles on indium-tin oxide (ITO) electrodes. First of all, Pd nanoparticles were electrodeposited on ITO via one step electrodeposition technique. Furthermore, Au was electrodeposited on Pd. Finally, Co was electrodeposited on Au and Pd electrodeposited ITO electrode via stepwise electrodeposition techniqu...
Chiral tertiary alcohols were obtained with good yields and enantioselectivities via a catalytic Reformatsky reaction with ketones, including the challenging diaryl ketones, using chiral BINOL derivatives.
Here we report the in situ generation of transient allylic boronic species, by reacting TMSCHN2 and E-vinyl boronic acids, followed by their subsequent trapping with aldehydes as electrophiles to yield homoallylic alcohols. This metal-free reaction was initially discovered by the use of a flow chemistry approach to generate a variety of homoallylic alcohols in a straightforward fashion and then...
The diarylalkenyl propargylic complex framework has been found in many natural products and medicinal regents. Herein, we have disclosed an unprecedented FeCl(3) catalyzed ene-type reaction of propargylic alcohols with 1,1-diaryl alkenes which enabled us to furnish a diarylalkenyl propargylic complex framework in moderate to high chemical yields (up to 98%).
unsubstituted phthalocyanines of co, fe and mn supported on zinc oxide nanoparticles were prepared and were well characterized with x-ray diffraction (xrd) and scanning electron microscopy (sem). the oxidation of alcohols with tert-butylhydroperoxide (tbhp), in the presence of metallophthalocyanines (mpc) supported on zinc oxide nanoparticles was investigated. these mpc/zno nanocomposites were ...
background: religious beliefs, access to alcohol and country rules clearly have impact on people's attitudes towards alcohol consumption. in this large study, sociological perspectives of people have been assessed about the effects of alcohol on some of common health problems. methods: in this survey, 143 real estate owners in city of mashhad were randomly selected and asked to give our questio...
background: public health burden from hazardous and harmful use of alcohol warrants drastic action throughout the world. although less alcohol related harm is anticipated in islamic countries, unrecorded alcohol remains a considerable concern which needs intelligent and realistic policy options. methods: in a descriptive study, records of chemically analyzed samples of alcohol obtained from ma...
A new synthesis of a-hydroxycarboxylates and 2-hydroxybenzoates based on the reaction of acetonides of a-hydroxycarboxylic acids and 2-hydroxybenzoic acid with sodium alkoxides in the corresponding alcohols as solvent is described. In general, decreasing the steric hindrance of the reactants and increasing the boiling points of alcohols increased the yiel...
T3P/DMSO is shown to be an effective and mild reagent for the one-pot synthesis of furo[2,3-d]pyrimidine-2,4(1H,3H)-diones from a variety of alcohols. Alcohols are oxidized in situ to aldehydes under mild conditions, which undergo a three-component reaction with N,N'-dimethylbarbituric acid and various isocyanides to afford furo[2,3-d]pyrimidine-2,4(1H,3H)-diones in good yields.
