A modular synthesis provides access to a series of new tris(pyrazolyl)borate ligands <sup>XpyMe</sup>TpK that possess a single functionalized pendant pyridyl (py) or pyrimidyl (pyd) arm designed to engage in tunable intramolecular H-bonding to metal–bound functionalities. To illustrate such H-bonding interactions, a series of [<sup>XpyMe</sup>TpCu]<sub>2</sub>(𝜇–OH)<sub>2</sub>(<b>6a</b><b>–6e</b>) complexes were synthesized from the corresponding <sup>XpyMe</sup>TpCu–OAc (<b>5a–5e</b>) complexes. Single crystal X-ray structures of three new dinuclear [<sup>XpyMe</sup>TpCu]<sub>2</sub>(𝜇–OH)<sub>2</sub>complexes reveal H-bonding between the pendant heterocycle and bridging hydroxide ligands while the donor arm engages the copper center in an unusual monomeric <sup>DMAPMe</sup>TpCu–OH complex. Vibrational studies (IR) of each bridging hydroxide complex reveal reduced 𝜈<sub>OH </sub>frequencies that tracks with the H-bond accepting ability of the pendant arm.

AbstractOily water contamination has been sighted as one of the most global environmental pollution. Herein, copper hydroxide nanorods layer was constructed onto cellulosic filter paper surface cured with polydopamine, Ag nanoparticles, and Cu NPs through immersion method. This work has been aimed to produce a superhydrophobic and superoleophilic cellulosic filter paper. The structure, crystalline, and morphological properties of these modified cellulosic filter paper were investigated. Scanning electron microscope images confirmed that the modified surface was rougher compared with the pristine surface. The contact angle measurement confirmed the hydrophobic nature of these modified surfaces with a water contact angle of 169.7°. The absorption capacity was 8.2 g/g for diesel oil and the separation efficiency was higher than 99%. It was noted that the flux in the case of low viscosity solvent as n-hexane was 9663.5 Lm−2 h−1, while for the viscous oil as diesel was 1452.7 Lm−2 h−1.

The glucosinolate, sinigrin (allyl- or 2-propenyl glucosinolate), present in several Gruciferae, was incorporated in varying concentrations into four different diet background mixtures to study the behavioural reactions of Mamestra configurata and Trichoplusia ni. Sinigrin concentrations were chosen to mimic normal levels in naturally occurring cruciferous plants, or to represent a plant during a particular stage in its growth cycle. One diet background mixture contained potassium chloride (KC1) and no stimulatory sugar or sugar alcohol, two backgrounds contained KC1 and a single sugar or sugar alcohol (sucrose or inositol, respectively), and the fourth background contained KC1 and both sugar and sugar alcohol (sucrose and inositol, respectively). Sinigrin acted primarily to reduce (deter) feeding in all backgrounds, although the effect varied with sinigrin concentration, background and species. When inositol or sucrose was included in the mixture, the deterrent effect of sinigrin was decreased in both species. When inositol and sucrose were present, suppression of the deterrent effect of sinigrin was greatest for M. configurata . The effects of mixtures were not predictable from a knowledge of the action of individual components. Differences observed between species may reflect different sensory capabilities.

The preparation of the related 6- methyl-1H-pyrrolo[2,3-c]pyridin-7(6H)-one (12) through a Lewis-acid- catalysed cyclization of the amide acetal (7) is also described.
