Abstract:
The structure of cucurbit[6]uril (CB[6]), as a fascinating supramolecular receptor, is regarded as ‘indestructible’. Herein, we investigated the hydrolysis of CB[6] catalysed by alkali. Our results showed that CB[6] was easily hydrolysed in 30% NaOH at 160°C within 3 h. Separation and purification of hydrolytic products demonstrated the presence of NH 3 , CO 2 , HCOONa, glycine and hydantoic acid. Based on the studies of the hydrolysis of substances similar to CB[6] including 4,5-dihydroxyethyleneurea, glycoluril and glycoluril dimer, we proposed that a plausible reaction mechanism involved a

Abstract:
Attempts to hydrolyse the nitrile group of 2-aminoadamantane-2-carbonitrile by mineral acid or alkali have been unsuccessful. However, treatment of the aminonitrile with benzaldehyde in alkaline solution gives the benzal derivative of the α-aminoamide, readily hydrolysed to the α-aminoamide. Alternatively, benzoylation of the amino group followed by acid hydrolysis gives successively the α-benzamido acid and the α-amino acid. Possible mechanisms for these facilitated hydrolyses are advanced.

Florpyrauxifen-benzyl is a novel herbicide used to control weeds in paddy fields. To clarify and evaluate its hydrolytic behavior and safety in water environments, its hydrolytic characteristics were investigated under varying temperatures, pH values, initial mass concentrations and water types, as well as the effects of 40 environmental factors such as microplastics (MPs) and disposable face masks (DFMs). Meanwhile, hydrolytic products were identified by UPLC-QTOF-MS/MS, and its hydrolytic pathways were proposed. The effects of MPs and DFMs on hydrolytic products and pathways were also invest

Abstract:
The mechanisms given in textbooks for both ester and amide hydrolysis in acid media are in need of revision. To illustrate this, benzimidates were chosen as model compounds for oxygen protonated benzamides. In aqueous sulfuric acid media they hydrolyze either by a mechanism involving attack of two water molecules at the carbonyl carbon to give a neutral tetrahedral intermediate directly, as in ester hydrolysis, or by an SN2 attack of two water molecules at the alkyl group of the alkoxy oxygen to form the corresponding amide, or by both mechanisms, depending on the structure of the benzimidate.

Furthermore, it is very likely that the enzyme has two alternative pathways for the hydrolysis of phytic acid, resulting in two different myo-inositol trisphosphate end products: Ins(2,4,6)P3 and Ins(1,3,5)P3.

The application of MIDA boronates (MIDA = N-methyliminodiacetic acid) in Suzuki- Miyaura reactions has increased over the last years. This is mainly because in many cases, the replacement of the boronic acid for the respective MIDA boronate has a positive result in the reaction yield. The key feature that makes MIDA boronates efficient coupling partners is that they can undergo a slow hydrolysis reaction under Suzuki-Miyaura conditions, which generates the boronic acid in situ. The control of the hydrolysis rate is crucial to keep a low concentration of the boronic acid to avoid some of the si

The catalytic cycle of nitrogenase involves binding of the Fe protein to each αβ catalytic half of the MoFe protein, electron transfer followed by ATP hydrolysis, Pi release and eventually dissociation of the two proteins. This cycle has to be repeated eight consecutive times to reduce one molecule of N2. The two catalytic halves of the MoFe protein had been considered to be independent of each other.

Due to this β-lactam resistant characteristics and the ease of horizontal gene transfer between bacteria, NDM-1 producing bacteria poses a great threat to public health.

Abstract The mechanisms of corrosion inhibition of mild steel by phosphate esters in a CO2 containing environment is studied by using various inhibitor solution characterization techniques (residual analysis, dynamic surface tension, emulsion tendency). Corrosion inhibition and inhibitor film persistancy is monitored over time by using a rotating cylinder electrode (RCE) system and linear polarization resistance (LPR) technique. Corrosion rate-time/concentration profiles are obtained for all phosphate esters studied. Optical profilometry is used to assess surface microstructure as related to i

Abstract:
Abstract Crevice corrosion involves a number of simultaneous and interacting operations, including mass transfer processes, production of metal ions within the crevice and hydrolysis reactions, resulting in a very aggressive solution from the point of view of corrosion. These intermediary corrosion processes are in a complex interdependence and they imply a number of important parameters, including both the crevice gap and depth. The major goal of this paper was development of a mathematical model for the calculation of the impurities concentrations (Na+, Cl-, Fe2+) into crevices and experimen

Abstract:
Abstract The process of crevice corrosion consists of anodic metal dissolution from the alloy to the crevice solution, cathodic reduction of oxygen on the bold surface of the metal outside the crevice, metal ion hydrolysis reactions, and mass transfer between the crevice solution and the bulk solution. The mass transfer process mechanisms are ionic migration and diffusion. An improved mathematical model has been developed for the numerical simulation of the incubation period of crevice corrosion. The model utilizes a new equation for the transport processes, which includes both ionic migration
