Abstract An environmentallyfriendly method for the construction of C(sp2)-CN bond on water has been described, and (Z)-2-(2-oxoindolin-3-ylidene)-2-arylacetonitriles were synthesized by using CeCl3· 7H2O as a catalyst. The reaction offers access to alkenyl nitriles in good-to-excellent yield. The investigations will be beneficial to reduce the use of toxic organic solvents and explore the efficient
