Using a novel dynamic covalent approach relying on reversible hydrazone formation, a purely organic 3-dimensional prismatic cage was developed in water at elevated temperatures. By lowering the temperature, the hydrazone bond becomes kinetically inert. This self-assembled cage acts as an effective receptor for donor-acceptor pairs, whose interactions are weak in the absence of the cage.
the seasonal variation of volatile oil compositions (vocs) from fresh flowers of persian musk rose was investigated by combi pal headspace techniques. in this study, a total number of 21 vocs were detected by headspace on the combi pal system and gas chromatography-mass spectrometry (hs-gc/ms) from rosa moschata herrm. at different seasons which was representing 92.53-99.37% of total vocs. the ...
New 1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives, 14-23, were prepared from the ketones 1-5 via the corresponding semicarbazones or hydrazones 6-12. The Hurd-Mori and Lalezari methods were used, respectively, for the preparation of these 1,2,3-thiadiazole and 1,2,3-selenadiazole derivatives. The intermediate 13 was also trapped, separated and fully characterized. These derivatives are ...
