HKUST-1 (HKUST ⇒ Hong Kong University of Science and Technology), [1] which is also called MOF-199, [2] is a material in the class of metal-organic frameworks (MOFs). Metal-organic frameworks are crystalline materials, in which metals are linked by ligands (so-called linker molecules) to form repeating coordination motives extending in three ...
As one might expect, given the greater Lewis acidity of Cr(III) vs. Cu(II), MIL-101 is much more active than HKUST-1 as a catalyst for the cyanosilylation of aldehydes. Additionally, the Kaskel group observed that the catalytic sites of MIL-101, in contrast to those of HKUST-1, are immune to unwanted reduction by benzaldehyde.
The HKUST Learning Commons provides ~600 seats and has 5 zones: Group Study, Open Study, Refreshment, Teaching, and The Creative Media Zone. [9] The Library and its staff were very active in supporting the university in the University Grants Committee (Hong Kong)'s Hong Kong Research Assessment Exercise of 2014. [10]
Sonochemical synthesis, which allows nucleation reactions to proceed rapidly through acoustic generation of localized heat and pressure, has been explored as a way to shorten synthesis times. [ 32 ] [ 33 ] As with the case of zeolites, microwave-assisted synthesis has also been of interest for the rapid synthesis of ZIFs.
Click chemistry is an approach to chemical synthesis that emphasizes efficiency, simplicity, selectivity, and modularity in chemical processes used to join molecular building blocks. It includes both the development and use of "click reactions", a set of simple, biocompatible chemical reactions that meet specific criteria like high yield, fast ...
The Sharpless epoxidation is viable with a large range of primary and secondary alkenic alcohols. Furthermore, with the exception noted above, a given dialkyl tartrate will preferentially add to the same face independent of the substitution on the alkene.To demonstrate the synthetic utility of the Sharpless epoxidation, the Sharpless group created synthetic intermediates of various natural ...
In organic chemistry, the Arndt–Eistert reaction is the conversion of a carboxylic acid to its homologue.It is named for the German chemists Fritz Arndt (1885–1969) and Bernd Eistert (1902–1978).
The main example is provided by silver perchlorate (and related salts), which dissolve in liquid arenes and crystallize with arene ligands. The strength of the metal-arene interaction is weak as indicated by the long Ag-C bond lengths and the nearly unperturbed nature of the arene.
