A one‐pot synthesis of indenones, was presented. The reaction involved palladium catalyzed annulation of ortho‐halobenzaldehydes with internal alkynes. Notably, this process was successful in water as the sole green solvent. Significantly, unlike earlier reports, this protocol showed excellent regioselectivity with unsymmetrical alkylarylacetylenes. Further, the strategy was extended to a one‐pot synthesis
