Gold(I) Phosphine/Phosphido‐Borohydride Complexes

European Journal of Inorganic Chemistry, EarlyView.
Synthesis, structure, and electrochemical characteristics of a homologous series of gold(I) complexes featuring phosphine and phosphido–borohydride ligands. A homologous series of linear, mononuclear gold(I) phosphine/phosphido‐borohydride complexes, encompassing [Au(PR3)2]+ 1, [Au(PR3)(PR2BH3)] 2 and [Au(PR2BH3)2]– 3 (R = tBu, Ad), has been prepared ...

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

European Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

Fast Reduction of Nitroalkenes Into Nitroalkanes Under Continuous‐Flow Chemical Conditions

European Journal of Organic Chemistry, EarlyView.
Flow chemical synthesis was employed for the reduction of nitroalkenes to the corresponding nitroalkanes using sodium borohydride as the reducing agent. The reaction proceeds in only 150 s, affording products from good‐to‐excellent yields (61–96%). Herein, we describe an efficient and rapid continuous‐flow reduction of nitroalkenes to nitroalkanes.

Hydrogen production by hydrolysis of sodium borohydride for PEM fuel cells feeding [PDF]

, 2008
In this work, hydrogen is produced by a hydrolysis process that uses sodium borohydride as a hydrogen carrier and storage media. High purity hydrogen is obtained at low temperatures with high volumetric and gravimetric storage efficiencies; reaction ...

A personal 360° view of applications of ‘biomimetic’ molecular recognition

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Emergence of a short peptide based reductase via activation of the model hydride rich cofactor

Nature Communications
In extant biology, large and complex enzymes employ low molecular weight cofactors such as dihydronicotinamides as efficient hydride transfer agents and electron carriers for the regulation of critical metabolic processes.

Development of an Efficient and Scalable Process for Preparing Timolol N‐Nitrosamine Impurities B, C, E, H, I, J, and Their ADMET Evaluation

Journal of Heterocyclic Chemistry, EarlyView.
N‐nitrosamine impurities (B, C, E, H, I, J) of timolol maleate are easily synthesized from diethyl malonate and 3,4‐dichloro‐1,2,5‐thiadiazole. Good yields and precise impurity profiling are made possible by the effective technique, which also ensures pharmaceutical safety and strengthens regulatory compliance.

Development of Selective Plane Illumination Surface Enhanced Raman Scattering Spectral Microscopy for Improved Cellular Imaging

Journal of Raman Spectroscopy, EarlyView.
Selective plane illumination (SPI) is combined with SERS spectral imaging to reduce background, improve image contrast, and enable improved spectroscopy from molecules on the surface of nanoparticles. This approach provides improved imaging and spectroscopy from nanoparticles in complex environments, such as biological cells.

Photooxidation of 18‐Carbon Polyunsaturated Fatty Acids to Prepare Mono‐Hydroxylated Octadecanoids

Lipids, EarlyView.
We developed a fast and simple one‐step synthetic strategy to produce mono‐hydroxylated metabolites based on the photosensitized oxidation of 18‐carbon polyunsaturated fatty acids (PUFAs). This approach could likely be extended to other PUFAs, suggesting that photosensitized oxidation could be employed to rapidly prepare hydroperoxides from multiple ...
