A simple and versatile method for the synthesis of 1,5-benzodiazepines from o-phenylenediamine and ketones in the presence of solvents and under solvent-free co
The conventional methods of edge detection can roughly delineate edge position of geological bodies,but there are still some problems such as low detection accuracy and being susceptible to noise inte
CeO2 nanocrystals were synthesized by a simple precipitation method and calcination at 600 ℃. (NH4)2Ce(NO3)6 and ammonia were used as precursors. The CeO2 nano
A new catalytic procedure for the chemoselective oxidation of sulfides to sulfoxides was studied. A variety of aliphatic and aromatic sulfldes were subjected to
