An efficient method for the synthesis of substituted 1(2H)‐isoquinolone derivatives via nickel‐catalyzed annulation of substituted 2‐halobenzamidines with aryl alkynes in the presence of water is described. Benzo[4,5]imidazo[2,1‐a]isoquinolines were formed as the dominated products when dry dimethyl sulfoxide was used as the solvent. Furthermore, when benzyl substituted amidines were used as the substrates
