A facile and highly efficient chemoselective reduction of α,β‐unsaturated amides leading to saturated amide has been described. In situ generated nickel boride was found to act as an efficient reagent for the conjugate reduction. The reaction proceeds smoothly under an inert atmosphere at ambient temperature with a moderate to good yield. Both aliphatic and aromatic α,β‐unsaturated amides were found to be compatible with the reaction protocol.

An electrochemical method was developed to accomplish the reagentless synthesis of 4,5-disubstituted triazole derivatives employing secondary propargyl alcohol as C-3 synthon and sodium azide as cycloaddition counterpart. The reaction was conducted at room temperature in an undivided cell with a constant current using a pencil graphite (C) anode and stainless-steel cathode in a MeCN solvent system. The proposed reaction mechanism was convincingly established by carrying out a series of control experiments and further supported by electrochemical and density functional theory (DFT) studies.
