Nitroalkenes and 6-nitro-Delta(5)-steroids have been converted regioselectively and in good yields into carbonyl compounds and 6-oxo steroids, respectively, by the SnCl2 . 2H(2)O-Mg-H2O system in tetrahydrofuran.

The kinetics of base hydrolysis of a series of (halogeno)(amine)cobalt(III) complexes, cis-[(en)(2)Co(B)X](2+) (B = NH3, CH3NH2, CH3CH2NH2, C6H5CH2NH2, C6H11NH2, imidazole, N-methylimidazole, benzimidazole, CH3CH(OH)CH2NH2, ...

Aluminothermic reduction of metal oxides is an established industrial process. However this reaction often requires skill because there are some procedural technique which the operator is required to know. Essentially, the ...

In this paper an attempt has been made to study the effect of using chemical additives on grinding and flotation of thermal coal containing 40% ash. The mill products are analysed by the new technique of low temperature ...
