Catalytic Application of High Valent Oxo-Rhenium Metal

Development of mild and efficient catalytic systems is always a quest for synthetic organic chemist. In this regard, transition metal complexes play a very crucial role. However, as broadly as the low valent transition metal complexes are emphasized in catalysis, the high valent transition metal complexes are not. Nevertheless, high valent transition metal oxides are air and moisture stable compared to low valent transition metal complexes; and therefore, it will be much attractive catalyst for sustainable and industrial developments. However, those are mostly use for oxidation or oxygen transfer reactions as they are in high oxidation state. Recently a considerable attention has been paid to utilize the stable high valent oxo-metals in various organic transformations, other than oxidation reactions. In this context, high valent oxo-rhenium complexes have proven to be mild and non-toxic nature. In this book, we have explored the catalytic activity of many high valent oxo-rhenium complexes in various organic transformations, other than oxidation reactions.
