Copper(ii) tetrasulfophthalocyanine supported on three-dimensional nitrogen-doped graphene-based frameworks was synthesized and introduced as a bifunctional catalyst for selective aerobic oxidation of alkyl arenes and alcohols to the corresponding carbonyl compounds. The ease of catalyst separation, high turnover, low catalyst loading and recyclability could potentially render it applicable in ...

Diaryliodonium salts are demonstrated as efficient arylating agents of aliphatic alcohols under metal-free conditions. The reaction proceeds at room temperature within 90 min to give alkyl aryl ethers in good to excellent yields. Aryl groups with electron-withdrawing substituents are transferred most efficiently, and unsymmetric iodonium salts give chemoselective arylations. The methodology has...

• A Cu-catalyzed 100% atom–efficient amidation and esterification reaction based on the of cyclopropenones with amines or alcohols, is shown. Both soluble solid Cu catalysts are catalytically competent, a Cu-containing metal–organic framework (MOF) particularly active reusable. The can be performed in variety solvents conditions, including water at different pHs, which defined as click reaction...

Alkyl hydroperoxides are reduced to alcohols in the presence of DPNH and homogeneous rubredoxin and rubredoxin-DPN reductase from Pseudomonas oleovorans. The reaction does not occur when TPNH is substituted for DPNH or when rubredoxins from anaerobic bacteria are substituted for the P. oleovorans nonheme iron protein. The reaction appears to have broad substrate specificity; 1-octyl, 2-octyl, c...

Highly efficient iridium catalyzed asymmetric transfer hydrogenation of simple ketones with ethanol as a hydrogen donor has been developed. By using chiral spiro iridium catalysts (S)- a series of alkyl aryl ketones were hydrogenated to chiral alcohols with up to 98% ee.

An electrochemical system has been developed in order to assay the effect of hydrophobic molecules on the bioluminescence of bacterial luciferase (BL). The inhibition of BL luminescence by the long-chain n-alkyl alcohol has been examined using this system. The 1-heptanol, 1-octanol, 1-nonanol, 1-decanol, 1-undecanol and 1-dodecanol inhibited the BL reaction in a dose-dependent manner. The IC(50...

Substituent effects have been used as a means of probing the nature of the transition state for C–I bond cleavage on the Pd(111) surface. The barriers to C–I cleavage (1EC–I) have been measured in a set of 10 different alkyl and fluoroalkyl iodides (CH3I, CF3I, CH3CH2I, CF3CH2I, CF2HCF2I, CH3CH2CH2I, CF3CH2CH2I, CF3CF2CH2I, (CH3)2CHI, and (CH3)3CI ) on Pd(111). These measurements were performed...
