Abstract A transitionmetal–free process, promoted by sodium borohydride, has been developed for convenient and selective hydration of nitriles to corresponding amides. The present process converts the aromatic, aliphatic, and heteroaromatic nitriles with wide functional group tolerance. The regioselective hydration of one nitrile moiety in the presence of an other nitrile group makes high impact in
An efficient hydration of organonitriles to the corresponding amides was accomplished using 1,3-dimethylimidazolium hydrogen carbonate as an organocatalyst. The developed catalytic method was also applicable for the synthesis of metal phthalocyanines.

An unusual red-shift of phthalocyanine Q-band upon aggregation in non-aqueous media has been observed for antimony(III) derivative and has been studied by using optical absorption and magnetic circular dichroism spectroscopy.
