The development of methods for the introduction of trifluoromethyl groups into functionalized molecules is of great importance due to their presence in many top-selling pharmaceuticals, agrochemicals, and functional materials. Trifluoromethyl groups are known to impart desirable properties, such as higher metabolic stability, increased lipophilicity, and stronger dipole moments to druglike mole...

Abstract 5-NaNT was the raw key material of copper(I) 5-nitrotetrazolate (DBX-1) and tetraaminecis-bis(5-nitrotetrazolato) cobalt(III) perchlorate (BNCP), which prepared from 5-AT by Sandmeyer reaction. This reaction usually happened slightly blast due to release heat nitrogen gas during whole procession. In order enhance safety reaction, differential scanning calorimetry (DSC) used measure exo...

SINCE the year 1889, when von Mering and Minkowski (1) preduced severe and fatal diabetes by total removal of the pancreas in dogs, many investigators have endeavoured to obtain some beneficial effect in diabetes mellitus, either by feeding pancreas, or by administration of pancreatic extracts. Minkowski, Sandmeyer (2), Pfluger (3) and others found that feeding pancreas was followed by negative...
