Heteroaryl substituted allyl and homoallyl alcohols were synthesised with two different method. Synthesis of bis-allyl ethers and homoallyl ethers were carried out via reaction of allyl bromide with allyl alcohols and homoallyl alcohols, respectively. [2.3]-Wittig Rearrangement reactions of heteroaryl substituted bis-allyl ethers were investigated using GC/MS techniques. In these reactions two ...

We report a mild and environmentally benign method for the synthesis of tertiary amines using alcohols as the alkylating reagents. Not only secondary amines such as piperazines but also amino acids and amino alcohols can be N-alkylated selectively. For N,O-benzyl protected amino alcohols, both N,O-de-benzylation and N-methylation were achieved in one-pot.

A sodium dodecyl sulfate modified carbon paste electrode (SDS/CPE) was developed in this work based on the surface modification method. The modified electrode was prepared by immersing SDS/CPE in a nickel nitrate solution. This electrode showed a strong accumulation ability toward nickel ions. Then modified electrode was conditioned by potential recycling in a potential range of 0.2–0.8 V (vs. ...

Primary carbohydrate amines at primary and secondary carbons are alkylated by alcohols in the presence of [Cp*IrCl(2)](2). When primary carbohydrate alcohols are used as the coupling partners and in the presence of Cs(2)CO(3), amine-linked pseudodisaccharides are obtained. Secondary carbohydrate alcohols are unaffected under these conditions, which allows regioselective reactions.

Well-defined unnatural dipeptide-alcohols based on a cis-2,5-disubstitued pyrrolidine backbone were synthesized from commercially available starting materials meso-diethyl-2,5-dibromoadipate, (S)-(-)-1-phenylethylamine, and phenylalaninol. The structures of these unnatural dipeptide-alcohols are supported by HRMS, 1H- and 13C-NMR spectroscopy. These unnatural dipeptide-alcohols can act as build...

In this study, Pd/C, Cu/C, and a series of PdCu/C bimetallic electrocatalysts were prepared by microwave-assisted modified polyol method to determine glycerol electrooxidation reaction (GOR) activities. The effect microwave duration on catalyst structure GOR activity was investigated catalysts. Also, commercial Pd/C (com-Pd/C) used compare catalytic activities with samples. Electrocatalysts cha...

The different weight ratios of Pd to Pt, i.e., 16:4, 10:10, 4:16 in Pd-Pt/C and (20 wt. %)/C electrocatalysts with low metal loading were synthesized for glycerol electrooxidation an air breathing microfluidic fuel cell (MFC). performance on Pd-Pt (16:4)/C anode electrocatalyst was found best among all the tested. single when tested at a temperature 35°C using (16:4)/C, showed maximum open cir...

Abstract The present experimental study used a successful advanced electrochemical oxidation process (AEOP) and parallel-plate reactor to investigate the potential of (EO) treatment method for real produced wastewater by Al-Samawah petroleum refinery. In oxidation, several electrodes type were employed, with carbon felt graphite plate serving as anode. Tests total organic compounds chemical oxy...

We demonstrate an efficient enantioselective oxidation of secondary alcohols catalyzed by Mn(III)-salen complex using N-bromosuccinimide (NBS) as the oxidant. The new protocol is very efficient for the oxidative kinetic resolution of a variety of secondary alcohols, including ortho-substituted benzylic alcohols.
