Engineering fluorination.
study that has traditionally focused on mapping small-molecule metabolites. As we become aware of an increasing number of examples of peptide metabolites that regulate key biological processes, we will need to further direct our attention toward analytical methods that allow pools of peptide metabolites to be monitored. The study in this issue provides a critical step forward in the development...
متن کاملFluorination in the Community
یکی از مهمترین دست آوردهای تکنولوژی غذایی، تصفیه شکر از نیشکر و چغندر بوده است. بین سال های ۱۸۷۰ و ۱۹۱۰، شکر یک ماده غذایی ارزان قیمت شد و به خاطر شیرینی، در دسترس بودن به اشکال مختلف و مفید بودن به عنوان یک ماده غذایی قابل نگهداری به خوبی مورد قبول واقع شد. ولی نتیجه بعدی و ناشناخته این دسترسی آسان به شکر، افزایش خرابی و پوسیدگی دندانها بود. بررسی های اپیدمیولوژیکی نشان داد که تا سال های ۱۹۳۰ ...
متن کاملFluorination of CNx Nanotubes
Multiwall CNx nanotubes have been prepared by thermal decomposition of acetonitrile over Co/Ni catalytic particles. The fluorination of nanotubes was performed at roomtemperature by using a gaseous mixture of BrF3 and Br2. Transmission electron microscopy (TEM) and x-ray diffraction (XRD) indicated that only the outer shells of CNx nanotubes were fluorinated, whereas the inner shells remained i...
متن کاملIron(II)-catalyzed benzylic fluorination.
Direct C-F functionalization of benzylic sp(3) C-H bonds is a synthetic challenge that has yet to be propitiously overcome. A mild, one-pot synthesis of monofluorinated benzylic substrates is reported with commercially available iron(II) acetylacetonate and Selectfluor in good to excellent yields and selectivity. A convenient route to β-fluorinated products of 3-aryl ketones is also highlighted...
متن کاملNew methods of specific fluorination.
The application of hypofluorites (fluoroxy-compounds), especially tnfluoromethyl hypofluorite, in the synthesis of fluorinated steroids is described. Hypofluorites are powerful but selective fluorinating agents with unusual electrophilic character. They should find considerable application not only in the synthesis of fluorinated steroids, but for preparation of fluorinated compounds of many di...
