The ruthenium-catalyzed oxidative allylation of aromatic and α,β-unsaturated carboxamides with allylic carbonates is described. These transformations proceed readily with complete linear γ-selectivity of substituted allylic carbonates.

The first report of the therapeutic intravenous use of sodium bicarbonate has been attributed by Kaehny and Anderson(l) to Thomas Latta who reported the practice of intravenous injections of bicarbonate (NaHCO3) and chloride into patients with cholera in 1832(2). Since the commercial availability of NaHCO3 for medical use in the late 1950s, there have been continuing efforts to clarify aspects ...

The enthalpy change for saturation of half the Fe(II1) binding sites was compared with the enthalpy change for saturation of the hall-saturated protein. In the presence of excess HCOBthese values were -10.90 f 0.19 Cal per mole of bound Fe(II1) and -10.43 f 0.76 Cal per mole of bound Fe(III), respectively. In the absence of HCOI-, corresponding values were -4.64 + 0.05 Cal per mole of bound Fe(...

An integrated carbon capture and utilization (ICCU) process present an ideal solution to address anthropogenic dioxide (CO2) emissions from fossil fuel-driven electricity production, allowing for capturing subsequent of CO2 instead current release into the atmosphere. Effective dual-functional materials (DFMs), through combination sorbents catalysts, can not only but also convert it higher-valu...

Abstract Current studies were performed to evaluate the physico-chemical characteristics and therapeutic potential of Chutrun thermal springs located in North-west Shigar Valley, Gilgit-Baltistan (Pakistan). Thermal with different mineral contents have been used by people for bathing health purposes since old timings. The water these contains elements like sodium, potassium, calcium, magnesium ...

Bicarbonate stimulates the activities of several class III adenylyl cyclases studied to date. However, we show here that bicarbonate decreased V(max) and substrate affinity in Cya1, a major adenylyl cyclase in the cyanobacterium Synechocystis sp. strain PCC 6803. This indicates that manifestation of the bicarbonate responsiveness is specifically modulated in Cya1.

The specific effects of some mutations that cause cystic fibrosis suggest that reduced HCO(3)(-) transport is the key to understanding cystic fibrosis pathology. But there is a puzzling discrepancy between measures of CFTR-mediated chloride conductance in expression systems and the sweat chloride values of patients.

An efficient method for the diastereo- and enantioselective construction of vicinal all-carbon quaternary stereocenters through palladium-catalyzed decarboxylative cycloaddition of vinylethylene carbonates with activated Michael acceptors was developed. By using a palladium complex generated in situ from [Pd2(dab)3]⋅CHCl3 and a phosphoramidite ligand as a catalyst under mild reaction conditions...

Anions are the negative components of most chemical structures and play many important physiological and pharmacological roles that are of interest to the anaesthetist. Their relevance is reviewed with a particular emphasis on the inorganic anions (halides, bicarbonate, phosphate and sulphate) and the significance and limitations of the anion gap. Organic anions (albumin, lactate) are also disc...

The effect of pH on the kinetics of photosynthesis, O(2) inhibition of photosynthesis, and photorespiration was examined with mesophyll cells isolated from soybean (Glycine max [L.] Merr.) leaves. At constant, subsaturating bicarbonate concentration (0.5 mm), O(2) inhibition of photosynthesis increased with increasing pH because high pH shifts the CO(2)-bicarbonate equilibrium toward bicarbonat...
