(AMD) problems are the most important environmental problems in sulphide mines especially mines which contain pyrite. Oxidation of sulphides in contact with air and water produces sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than

The Wittig reaction is a unique reaction that can be carried out in various ways as our prompt exemplifies. We will be primary focusing on the second of the three schemes. In The usual formation of an ylide occurs via Sn2 attack of a PR3 group on an alkyl halide‚ which is then followed by a strong base deprotonating of one of the hydrogens on the methyl which the PR3 attacked. Before we dive into the details of the reaction occurring in scheme 2 it will be important to understand the mechanism which
