متن کاملA simple and safe method for preparation of Mg(OH)2 nanorods in ambient air
Magnesium hydroxide Mg(OH)2 nanorods with diameters of 90±10nm and lengths of more than 2μms were prepared by a simple route at ~75oC in ambient air. The approach is based on reaction of magnesium powder and de-ionized water without the use of any harmful, toxic or corrosive reagents. Characterization using X-ray diffraction (XRD) shows single crystalline structure of Mg(O...

متن کاملSimple and Efficient Method for the Preparation of 5-Bromoisatins
Isatin, N-methyl isatin and N-benzylisatin were smoothly monobrominated in the 5-position by treatment with pyridinium bromochromate (PBC) in acetic acid medium. In the similar conditions indigo underwent bromination and oxidation to give 5-bromoisatin in high yield.
متن کاملrac-Methyl 4-azido-3-hydroxy-3-(2-nitrophenyl)butanoate
In the title compound, C(11)H(12)N(4)O(5), the mean plane through the nitro substituent on the benzene ring is inclined to the benzene mean plane by 85.8 (2)°, which avoids steric inter-actions with the ortho substituents. The hydr-oxy group is involved in bifurcated hydrogen bonds. The first is an intra-molecular O-H⋯O hydrogen bond, involving the ester carbonyl O atom, which gives rise to the...
