Well-Defined Noble Metal Single Sites in Zeolites as an Alternative to Catalysis by Insoluble Metal Salts

Insoluble precious metal chlorides in polymeric form (i.e., PtCl2, PdCl2, AuCl, RhCl3) are commonly used as catalysts for a plethora of organic reactions in solution. Here we show that only the minor soluble fraction of these precious metal chlorides (typically 5-30%) is catalytically active for the hydroamination, hydroalkoxylation, hydrosilylation, and cycloisomerization of alkynes and alkenes, and that the resting insoluble metal is catalytically useless. To circumvent this waste of precious metal and follow a rational design, we generate here well-dispersed Pt(II) and Pd(II) single sites on zeolite Y, with an exquisite control of the Lewis acidity, to catalyze different hydroaddition reactions to alkynes and alkenes with up to 104 catalytic cycles (at least 2 orders of magnitude superior to precious metal chlorides) and with high isolated yields (82-99%, >15 examples).

Selection of a potential diagnostic biomarker for HIV infection from a random library of non-biological synthetic peptoid oligomers

Non-biological synthetic oligomers can serve as ligands for antibodies. We hypothesized that a random combinatorial library of synthetic poly-N-substituted glycine oligomers, or peptoids, could represent a random ?shape library? in antigen space, and that some of these peptoids would be recognized by the antigen-binding pocket of disease-specific antibodies. We synthesized and screened a one bead one compound combinatorial library of peptoids, in which each bead displayed an 8-mer peptoid with ten possible different amines at each position (108 theoretical variants). By screening one million peptoid/beads we found 112 (approximately 1 in 10,000) that preferentially bound immunoglobulins from human sera known to be positive for anti-HIV antibodies. Reactive peptoids were then re-synthesized and rigorously evaluated in plate-based ELISAs. Four peptoids showed very good, and one showed excellent, properties for establishing a sero-diagnosis of HIV. These results demonstrate the feasibility of constructing sero-diagnostic assays for infectious diseases from libraries of random molecular shapes. In this study we sought a proof-of-principle that we could identify a potential diagnostic antibody ligand biomarker for an infectious disease in a random combinatorial library of 100 million peptoids. We believe that this is the first evidence that it is possible to develop sero-diagnostic assays ? for any infectious disease ? based on screening random libraries of non-biological molecular shapes.

Indoles via Knoevenagel-Hemetsberger reaction sequence

A series of substituted indoles have been synthesized by the sequential reaction of aromatic aldehydes with ethyl azidoacetate in the presence of sodium ethoxide to form the corresponding ethyl alpha-azido-beta-arylacrylates (Knoevenagel process) followed by a solvent mediated thermolysis (Hemetsberger process). The isolated yields of the ethyl alpha-azido-beta-arylacrylates were significantly increased when employing the sacrificial electrophile ethyl trifluoroacetate. 1H NMR and coupled 1H-13C NMR analysis of the ethyl alpha-azido-beta-arylacrylates indicate that the condensation is stereospecific – only the Z-isomer could be detected. Solvent mediated thermal treatment of the meta-substituted ethyl alpha-azido-beta- arylacrylates resulted in the formation of both the 5- and 7- substituted indoles – the 5-regioisomer being slightly favored over the 7-regioisomer. Analogous thermal treatment of (2Z, 2Z?)-diethyl 3,3?-(1,3- phenylene)bis(2-azidoacrylate) and (2Z, 2Z?)-diethyl 3,3?-(1,4- phenylene)bis(2-azidoacrylate) exclusively produced pyrroloindoles, diethyl 1,5-dihydropyrrolo[2,3-f]indole-2,6-dicarboxylate and diethyl 1,5-dihydropyrrolo[2,3-f]indole-2,6-dicarboxylate, respectively. Results are also reported which indicate that the alpha-azido-beta-arylacrylates can be used in the subsequent Hemetsberger indolization process without prior purification.

Br¡ãnsted acid-promoted formation of stabilized silylium ions for catalytic friedel-crafts C-H silylation

A counterintuitive approach to electrophilic aromatic substitution with silicon electrophiles is disclosed. A strong Br¡ãnsted acid that would usually promote the reverse reaction, i.e., protodesilylation, was found to initiate the C-H silylation of electron-rich (hetero)arenes with hydrosilanes. Protonation of the hydrosilane followed by liberation of dihydrogen is key to success, fulfilling two purposes: to generate the stabilized silylium ion and to remove the proton released from the Wheland intermediate.

Corrosion protection of mild steel in hydrochloric acid solutions in presence of 5-(Benzyloxy)indole – Monte Carlo simulation, weight loss and electrochemical studies

The inhibition effects of 5-(Benzyloxy)indole, noted 5BI on mild steel corrosion in 1.0 M HCl were studied with potentiodynamic polarization, electrochemical impedance spectroscopy techniques and weight loss studies. It was shown that 5BI act as good corrosion inhibitor for mild steel protection. The high inhibition efficiencies were attributed to the simple blocking effect by adsorption of inhibitor molecules on the steel surface. Molecular dynamics was carried out to establish mechanism of corrosion inhibition for mild steel with 5BI in acidic medium. The inhibition action of the compound was assumed to occur via adsorption on the steel surface through the active centers in the molecule following Langmuir isotherm model. The results indicated that the corrosion inhibition is due to the physical and chemical adsorption on the steel surface.

Sub and supercritical water oxidation of pharmaceutical wastewater

Sub and supercritical water oxidation (Sub- CWO & SCWO) technology has gained attention over the past few years due to near complete conversions at shorter residences times. A pharmaceutical sample containing variety of analgesics, antibiotics, antipyretics, antifungal, beta-blockers and drug intermediates contributing to overall total organic carbon (TOC) of 2017 ¡À 49 mg/L was collected from a nearby pharmaceutical industry for this research. The sample was subjected to sub and supercritical water oxidation both in batch and continuous processes. A maximum removal efficiency of 80.1% was achieved with excess oxidant (oxidation coefficient (OC 3)) at 400 C for 60 min residence time in batch reactor. The pharmaceutical sample was also processed in continuous supercritical water reactor by varying both temperature (400-550 C) and oxidant coefficient (0-2) at 23 MPa for 60 s residence time. With the operating temperature of 550 C and OC 2 resulted in maximum removal of the pharmaceutics with efficiency of 97.8%.
