N-Chlorosuccinimide (NCS)-mediated[2+2] cycloaddition and C-C triple bond cleavage/rearrangement reaction of yne-allenones and H2O as a nucleophilic reagent enabled the formation of 18 examples of 2,4,4-trichloronaphthalene-1(4H)-one derivatives with 55%~88% yields. The structures of these obtainable products were based on their NMR, IR and HRMS data, among which the structure of product 2e was confirmed by X-ray analysis. This metal-free transformation features mild conditions, simple operation and high reaction yields. It provides an effective and new protocol for the synthesis of trichloro-substituted naphthalene-1(4H)-ones.

Key words: yne-allenones, [2+2] cycloaddition, C-C triple bond cleavage/rearrangement, 2,4,4-trichloronaphthalene-1(4H)-ones
