2011年9月2日 · Benzil was initially selected for an X-ray diffuse scattering study aimed at understanding the influence of molecular flexibility on crystal packing and polymorphism [75]. In that study, a Monte Carlo model made of spring constants for describing effective intermolecular interactions, gave quantitative agreement with data obtained from four ...

On recasting benzil, it is possible to obtain a wide variety of utilities in pharmaceuticals, polymer, and material chemistry. This contemplation of the review gives a general perspective of reaction routes, mechanisms and highlights the conversions due to oxidation, and accentuates benzil as an emerging putative target.

2010年11月17日 · Benzils are used as building blocks for the synthesis of pharmaceuticals, 1 photoinitiators for the free-radical curing of polymer networks, 2 and precursors of porphyrins. 3 The direct oxidation of benzoins to benzils is a simple straightforward method and has been accomplished by using several oxidizing agents such as nitric acid, 4 ammonium nitrate …

2018年6月15日 · The crystals of benzil monohydrazone based Schiff bases were grown in ethanol and/or methanol solution through slow evaporation process and suitable crystals were collected and analyzed through single crystal X-rays diffraction analysis. The single-crystal structures with atom numbering scheme is illustrated in Fig. 1.

2009年3月1日 · Benzil is one of the important organic compounds that has been received a great deal of attention due to its practical applications, such as photosensitive agents and synthetic agents in organic and pharmaceutical chemistry [1], [2], [3]. The oxidation of benzoins is one of the most efficient and practical methods for the synthesis of benzils.

2002年3月28日 · In benzil reduction, the maximal activity was observed in the pH range between 6.0 and 8.0. In contrast, very low activity for benzoin oxidation in the presence of NADP + was detected. Thirdly, optimal temperature was measured (Fig. 3 B). The benzil reduction at pH 6.5 was high at temperatures ranging from 30 to 60 °C with a peak at 50 °C ...

2024年2月14日 · In this work, we report alkoxy substituted benzil based all organic room temperature phosphors which showed crystallization induced phosphorescence (CIP). Nine title compounds were prepared with various alkyl lengths (OC n H 2 n +1 : n = 8–16) and the effect of alkyl side group length on the phosphorescence performance was investigated, as ...

2011年4月8日 · Various benzil derivatives, bearing substituents on aromatic rings, can be stereoselectively reduced to chiral hydrobenzoin with a high enantiomeric excess and a good yield. Benzils with electron-donating substituents were reduced with excellent enantioselectivity but with lower reactivity, while the reduction of p -fluorobenzyl proceeded ...

2001年10月3日 · For benzil, this potential has been studied only by the AM1 method [33]. In the present work, the geometry of isolated benzil has been investigated using semi-empirical PM3 and DFT/6-31G ∗∗ calculations. The dependence of the relative energy on the O C–C O dihedral angle is shown in Fig. 1. Only one rather flat minimum is observed in the ...

2024年1月1日 · Benzil-PMMA hybrid nanofibers were fabricated by electrospinning technique. It contains the benzil nanocrystals embedded inside the polymer fiber. The morphological analysis shows the formation of smooth fibers of average diameter 470 nm. X-ray diffraction data confirmed the crystallisation of benzil molecules inside the PMMA fiber.
