Notwithstanding lack of ability to dissolve reactants, water exhibited superior performance to other media. 2-Methoxyethyl nitrite, which has been tailored for reactions in water, empowered this protocol. Chemoselective transformations of the products opens up access to a new chemical library. These results support the power of running organic reactions in water.
