The hydration of nitriles into the corresponding amides is very important in organic chemistry as well as in the chemical industry. There are a number of different methods for this conversion. Nitrile hydration is a classic transformation but one which is still difficult to achieve, even with the range of available reagents. Traditionally, various acids or bases were used as catalysts [1-9]. Transition metal catalyzed methods have been developed using Co [10,11], Mo [12], Ru [13-16], Rh [17,18], Pd [19,20], Ir [21] and Pt [22-24]. Homogeneous metal catalysis is frequently used in an industrial setting. Intimate catalyst substrate interaction, mild reaction conditions and an understanding of the catalytic process are recognized as main advantages. The catalytic hydration of nitriles (RCN) to carboxamides (RCONH2) represents a fundamentally important pathway to these products in both laboratory and industrial contexts [25-34]. Since the discovery of alumina-supported ruthenium hydroxide catalysts [Ru(OH)x/Al2O3] by Yamaguchi et al. [15] solid-supported ruthenium has become an important class of catalyst for nitrile hydration, demonstrating high selectivity for carboxamide formation as well as other practical advantages [35-50]. Although RuCl3·nH2O itself catalyzes nitrile hydration, the choice of solid support is critically important for achieving sufficient reactivity as well as for retaining Ru species on support [15,37]. Examples of supports successfully used for Ru species include inorganic Al2O3 [15], nanoferrite [35] and magnetic silica [36] as well as organic chitosan [51], amberlite [37] and Nafion [38]. However, these systems typically require the use of microwave irradiation [35-37,51] or high Silica-Sulfuric Acid: Novel, Simple, Efficient and Reusable Catalyst for Hydration of Nitrile to Amide
