Professors Armando Pombeiro and Fátima Guedes da Silva edited and written a few chapters of the book entitled "Alkane Functionalization" published by Wiley. Alkanes, in spite of being the major components of natural gas and oil and a highly rich natural carbon source, have been applied mainly as non-renewable fossil fuels where they are burnt and carbon (as carbon dioxide) is completely lost to the atmosphere with environmental problems. In fact, the inertness of alkanes has hampered their application as a feedstock in organic synthesis and such a potential overall approach concerns one of the greatest challenges in modern chemistry. The development of sustainable and direct catalytic processes to achieve functionalized products from alkanes, in good yields and selectivities under mild conditions, would be highly advantageous even in terms of simplicity, in comparison with the current multi-stage and often energy demanding processes used in industry for such organic products (e.g., alcohols, ketones, carboxylic acids, amines, amides, etc). This book gathers highly recognized researchers on the modes of catalytic functionalization of alkanes, covering the state-of-the-art in the field, under its modern perspectives. In the book cover, Alkane Functionalization is viewed as the blooming of an almond tree branch in Spring, where the alkane carbon framework becomes decorated with functional groups, namely bearing oxygen, nitrogen, carbon, boron, halo or other elements.
