Nickel boride has been reported as a convenient and efficient reagent in numerous transformations.1–5 It is superior to many other metal catalysts due to its low cost, ease of preparation and handling, non-pyrophoric nature and easy removal. Unlike its initial applications as a heterogeneous catalyst, nickel boride is used as a reducing agent without aid of hydrogen as it contains adsorbed hydrogen

A general route for the preparation of selenones (R2SeO2) is presented. This task is achieved through the quick and high-yielding reaction of selenides (R2Se) with HOF·CH3CN. The reaction tolerates some elusive electron-deficient and sterically hindered selenides. Some mechanistic aspects are also investigated and discussed.
